5-Year and 4-Year MD Programs in the Caribbean: How They Work
Compare 4-year, 5-year, 6-year, and 7-year Caribbean MD tracks. See St. George's University's entry requirements, MCAT rules, start dates, and interview steps.
A 4-year Caribbean MD program starts directly at MD Year 1 for applicants who already hold a bachelor's degree with science prerequisites, while a 5-year MD track starts one year earlier at Preclinical Year 3 for secondary school graduates with credentials like A-Levels or an IB Diploma. At St. George's University (SGU), the multi-track system spans 4-, 5-, 6-, and 7-year pathways that all feed into the same four-year medical curriculum and clinical network of over 85 affiliated hospitals and health systems in the United States, Canada, and the United Kingdom.

4-year vs 5-year+ Caribbean MD tracks at a glance
Caribbean medical schools that admit students both after college and straight from secondary school use a multi-track entry system. Instead of running separate medical degrees, they place you into a preclinical phase based on your academic credentials, and every track feeds into the same four-year Doctor of Medicine curriculum.
On St. George's University's School of Medicine admissions page, the tracks map directly to four entry points: Preclinical Year 1 (7-year track), Preclinical Year 2 (6-year track), Preclinical Year 3 (5-year track), and MD Year 1 (4-year program). Students can also pursue a BSc/MD Dual Degree option alongside the MD tracks, or graduate pathways such as the Dual MD/MPH and Dual MD/MSc programs.
If you are preparing for an upcoming admissions interview for any of these tracks, Confetto runs AI mock interviews with follow-up questions tailored to your background. Start your free week to practice your answers out loud before your interview date.
| Program or track | Entry point | Qualifying academic background |
|---|---|---|
| 4-Year MD Program | MD Year 1 | Bachelor's degree in the requisite sciences from an accredited university |
| 5-Year MD Track | Preclinical Year 3 | Advanced Levels (A-Levels), Full IB Diploma, Approved Foundation Programs, or All 10+2 India Senior Secondary School Certificate |
| 6-Year MD Track | Preclinical Year 2 | AS Levels, Baccalaureate, South Africa Matric, Higher School Exam, Irish Leaving Certificate, BTEC in sciences with Distinction, or High School Diploma with 90%+ average |
| 7-Year MD Track (Grenada only) | Preclinical Year 1 | IGCSE (minimum 6 subjects at B or better) or Secondary School and American High School Diploma |
How the 5-year MD track works (Preclinical Year 3 entry)
The 5-year MD track is built for students who completed advanced secondary school science curricula or an approved post-secondary foundation program, rather than a full bachelor's degree. Instead of spending three or four years in undergraduate college before applying to medical school, you enter directly at Preclinical Year 3.
Once you finish Preclinical Year 3, you join the standard four-year MD cohort.
SGU publishes exact subject and score rules for the four qualifications that grant entry into the 5-year MD track:
- Advanced Levels (A-Levels): You need at least 3 subjects with grades of A or B in biology, chemistry, and either math or physics. If you did not take math or physics at A-Levels, SGU may accept a strong third non-science subject as long as you show proof that you took math or physics at AS Level.
- Full IB Diploma: Requires a minimum total score of 32 points. At least 2 Higher Level (HL) subjects are required, which must include chemistry and biology with results of 5 or higher, and 3 HL science subjects are recommended.
- All 10+2 India Senior Secondary School Certificate: Requires a minimum 80% average across biology, chemistry, math, physics, and English. If you have not taken or completed math before matriculation, SGU notes that a pre-sessional math program may be necessary.
- Approved Foundation Programs: SGU recognizes and approves specific science and medical pathway foundation programs for direct entry into Preclinical Year 3.
How the 4-year MD program works (MD Year 1 entry)
If you already hold an undergraduate degree, you enter at MD Year 1 in the 4-year MD program. For US and Canadian applicants, SGU requires a bachelor's degree from an accredited college or university. For non-US and non-Canadian applicants entering the 4-year track, a bachelor's degree with a strong science background is necessary.
To see how prerequisite rules compare across other schools in the region, read our guide to Caribbean medical school requirements. At SGU, US and Canadian applicants to the 4-year MD program must complete six specific undergraduate prerequisite areas (or equivalencies confirmed with an SGU admissions officer at admissions@sgu.edu):
- General Biology or Zoology: One year with lab.
- Inorganic Chemistry (General or Physical): One year with lab.
- Organic Chemistry: One year with lab.
- Physics: One semester with lab.
- Mathematics: One semester of a 100-level college or university-level mathematics course.
- English: One semester.
6-year and 7-year MD tracks: earlier preclinical entry points
Show details
Students finishing high school without A-Levels or a 32-point IB Diploma do not qualify for Preclinical Year 3, so they enter earlier in the preclinical sequence. SGU splits these earlier pathways into the 6-year track and the 7-year track.
The 6-Year MD Track begins at Preclinical Year 2. The 7-Year MD Track is offered on the Grenada campus only and begins at Preclinical Year 1, covering all three preclinical years before the four-year MD curriculum.
- 6-Year MD Track (Preclinical Year 2) via American or Secondary High School Diploma: Requires an overall average of 90% or better with strong performance in science courses.
- 6-Year MD Track (Preclinical Year 2) via BTEC: Requires a BTEC Diploma in the appropriate sciences with grades of Distinction.
- 6-Year MD Track (Preclinical Year 2) via Further Education: Accepts AS Levels, Baccalaureate, South Africa Matric, Higher School Exam, or the Irish Leaving Certificate.
- 7-Year MD Track (Preclinical Year 1, Grenada only) via IGCSE: Requires grades of B or better in a minimum of 6 subjects, which must include biology, chemistry, math, physics, and English.
- 7-Year MD Track (Preclinical Year 1, Grenada only) via High School Diploma: Accepts a standard Secondary School or American High School Diploma.
Which track do you qualify for? A 4-step self-check
Use this four-step checklist, built by our team from SGU's published entry table, to find your exact starting point before you open an application.
- Step 1, Check if you hold a bachelor's degree: If you have a bachelor's degree from an accredited college or university plus the required undergraduate science labs (one year each of biology, inorganic chemistry, and organic chemistry, plus one semester each of physics, 100-level math, and English), you enter at MD Year 1 (4-Year MD Program).
- Step 2, Check for advanced secondary or foundation credentials: If you do not have a bachelor's degree, check if you hold 3 A-Levels at A or B (biology, chemistry, and math or physics, or a third non-science with AS-Level math or physics), a Full IB Diploma with at least 32 points and 5+ in HL biology and chemistry, an India 10+2 certificate with an 80%+ average in bio, chem, math, physics, and English, or an SGU-approved foundation program. Any of these places you at Preclinical Year 3 (5-Year MD Track).
- Step 3, Check for a 90%+ high school average or regional leaving certificate: If you have an American or secondary high school diploma with a 90% or higher overall average and strong sciences, a science BTEC with Distinction, AS Levels, Baccalaureate, South Africa Matric, Higher School Exam, or Irish Leaving Certificate, you enter at Preclinical Year 2 (6-Year MD Track).
- Step 4, Check IGCSE or standard high school completion: If you have at least 6 IGCSE subjects at grade B or better (including biology, chemistry, math, physics, and English) or a standard secondary/American high school diploma below the 90% mark, you enter at Preclinical Year 1 in Grenada (7-Year MD Track).
MCAT rules, English proficiency scores, and start dates
Whether you need the MCAT depends on your citizenship and where you apply from, not just the track you choose. If you are looking specifically for programs where you can apply without a test score, see our guide to Caribbean medical schools that don't require the MCAT.
At SGU (MCAT code 21303), US applicants must submit an MCAT score as part of their application. Canadian applicants are not required to submit an MCAT score unless they have already taken the MCAT or have a scheduled test date to take it. Applicants from outside North America are not required to submit an MCAT score.
SGU charges no application fee. You can apply directly through the online SGU Application or submit an existing AMCAS, AACOMAS, or TMDSAS application. Along with the application, you submit official transcripts from every college, university, or professional school attended, plus two letters of recommendation (or 1 Health Committee Letter of Recommendation).
Instead of a single fall intake, SGU runs three entry terms a year in January, April, and August (the April term is for the School of Medicine only). On SGU's admissions page, the listed 2027 start dates are January 18, 2027, April 7, 2027, and August 16, 2027, and the inquiry portal lists three campus options of interest: St. George's University in Grenada, Northumbria University in Newcastle (United Kingdom), and the University of Waterloo in Ontario (Canada).
Prospective students from countries not considered English-speaking under UK Visas and Immigration (UKVI) guidance must pass an approved English exam. You can request a waiver from SGU if you earned an undergraduate degree from an English-speaking country.
| Exam | Minimum overall score | Minimum band or section scores |
|---|---|---|
| IELTS Academic or UKVI | 7.0 Overall | 7.0 on each band |
| TOEFL (Internet-based) | 5 Overall | Listening 5, Reading 5, Speaking 4.5, Writing 5 |
| Password-Skills (same scoring as IELTS C1 Advanced / CAE) | 185 Overall | 185 in each band |
| Duolingo English Test (DET) | 130 Overall | 130 on each band |
| Kaplan Test of English (KTE) | 510 Overall | 510 on each band |
Curriculum, clinical hospital network, and residency placement
Once you reach MD Year 1, whether directly with a bachelor's degree or after finishing Preclinical Year 3, the curriculum is identical. SGU uses a systems-based curriculum in the basic sciences that includes small-group learning, hands-on clinical skills, virtual reality, and sonography.
For the clinical phase of the MD degree, SGU partners with over 85 affiliated hospitals and health systems across the United States, Canada, and the United Kingdom for clinical and ambulatory training. Throughout the basic science and clinical years, SGU's Office of Career Guidance (OCG) advises students on specialty selection, residency applications, and residency interviews, connecting graduates to an alumni network of more than 25,000 graduates worldwide.
SGU notes on its admissions page that its School of Medicine has been continuously accredited for decades, enabling students to be eligible to practice in the US, and publishes a US residency placement rate averaged over 2020 to 2024. Before applying to any Caribbean program, verify its current accrediting body status and US licensure eligibility in our guide to accredited Caribbean medical schools and compare outcomes across campuses in our guide to the best Caribbean medical schools.
The 3-stage admissions process and your interview
Every applicant to SGU's School of Medicine goes through a three-stage review managed by the Faculty Student Selection Committee and your assigned admissions officer and admissions coordinator.
Stage 1 is Initial Review. Once your application and supporting documents arrive, your admissions officer sends your file to the Faculty Student Selection Committee. Applicants are usually notified of their interview decision within 5 business days (occasionally the committee requests additional information first).
Stage 2 is The Interview. Conducted with SGU's professional interview team, the conversation explores how your background prepared you for medicine, what you learned from challenges, and how you match the committee's selection criteria. SGU advises applicants to test their camera and sound in a quiet space, dress professionally, and be ready to discuss specific strategies they developed after facing academic challenges.
Stage 3 is Final Review and Admission Decision. Your admissions officer sends your interview summary and complete file back to the Faculty Student Selection Committee for a holistic review. The committee issues one of three decisions: Admit, Admit with Provisions (where your admissions letter outlines specific conditions of your offer), or Not Admit.
When evaluating your file and your interview, the Faculty Student Selection Committee looks for nine specific attributes:
- Strong academic achievement or potential
- Empathy and compassion
- Motivation towards and demonstrated interest in the profession of medicine
- Ability to learn from mistakes or failures
- Critical thinking with problem-solving ability
- Strong communication skills and ability to work in a team
- Resilience and adaptability
- Sense of community responsibility
- Curiosity, dedication to lifelong learning, and sensitivity and openness to diversity

Practice question
SGU tells interviewees to be ready to discuss what they learned from an academic challenge and the strategies they developed moving forward. Tell me about a course or exam where you fell short of your goal, and what you changed afterward.
See an example answer
In my first term of A-Level chemistry, I earned a C on our organic mechanisms mock exam because I was studying the way I did for IGCSEs, by rereading my notes the week before the test. I could recognize reactions on paper, but I froze when the exam combined two steps I had not seen together. Right after getting that paper back, I met with my chemistry teacher to look at where my reasoning broke down. I changed two habits that week. First, I stopped rereading notes and started doing 20 minutes of synthesis problems every evening without looking at the mark scheme until I wrote out a full mechanism. Second, I formed a three-person study group where we took turns explaining one reaction pathway at the whiteboard every Friday. By the end of the year, I brought my final A-Level chemistry grade up to an A. More importantly, that experience taught me how to spot early when a study method is too passive, which is the exact habit I will rely on during the fast pace of Preclinical Year 3.
Example answer written by our team. The applicant is invented. This response works because it directly answers the prompt SGU highlights on its admissions page: it owns a specific academic shortfall without making excuses, names two concrete study changes, shows the measurable result, and connects the lesson to the workload of the 5-year MD track.
Frequently asked questions
What is the difference between a 4-year MD program and a 5-year MD track in the Caribbean?
At St. George's University, the 4-Year MD Program starts directly at MD Year 1 and requires a bachelor's degree with undergraduate science prerequisites. The 5-Year MD Track starts one year earlier at Preclinical Year 3 and is designed for students holding A-Levels, a Full IB Diploma, an All 10+2 India Senior Secondary Certificate, or an approved foundation program.
What A-Level or IB scores do I need for the 5-year MD track at SGU?
For A-Levels, you need at least 3 subjects with grades of A or B in biology, chemistry, and either math or physics (a strong third non-science subject may be accepted if you took math or physics at AS Level). For the Full IB Diploma, you need a minimum of 32 points and at least 2 HL subjects, including chemistry and biology, with scores of 5 or higher.
Can I enter a Caribbean medical school straight from an American high school?
Yes, through the 6-year or 7-year tracks rather than the 5-year track. At SGU, an American or Secondary High School Diploma with an overall average of 90% or better and strong science performance qualifies for the 6-Year MD Track (entering at Preclinical Year 2), while a standard American High School Diploma or 6 IGCSEs at grade B or better qualifies for the 7-Year MD Track in Grenada (entering at Preclinical Year 1).
Do I need to take the MCAT for a 4-year or 5-year Caribbean MD program?
At SGU, US applicants must submit an MCAT score (SGU's MCAT code is 21303). Canadian applicants only need to submit an MCAT score if they have already taken the exam or have a scheduled test date, and applicants from outside North America are not required to submit an MCAT score.
How long does it take to get an interview decision at St. George's University?
Once your application and supporting documents are sent to the Faculty Student Selection Committee for initial review, applicants are usually notified about their interview decision within 5 business days. After the interview, the committee reviews your complete file and issues an Admit, Admit with Provisions, or Not Admit decision.
