Best Casper Prep (2026): Acuity's Free Practice, Free Tools and Paid Prep Compared
Acuity's free practice test, then free Casper tools and paid prep (CasperPractice, StudyCasper, CasperBooster, Caspermate, BeMo), with prices from each site. We build Confetto.
The best Casper prep starts free: Acuity Insights' official practice test, in your Acuity account once you book Casper, shows the real format. It isn't scored, so add a tool that scores your practice answers, like CasperPractice, StudyCasper, BeMo or Casper Prep by Confetto.
Free tiers from CasperPractice.org, StudyCasper, CasperBooster, Caspermate and Casper Prep by Confetto let you try AI scoring before you pay, and BeMo's human coaching starts at CAD $1,997.
We build Confetto. Confetto is an AI mock interviewer for medical school and other healthcare program interviews (MMI, traditional, panel). Casper Prep by Confetto is its timed Casper practice, with video scenes and a score on every answer.

What does Acuity say about Casper prep?
Acuity runs Casper: 11 scenarios in two sections, video then typed, in 65 to 85 minutes. Its prep page recommends the official practice test in your Acuity Insights account, which is “designed to match the format and experience” of the test you booked and can be taken more than once.
Acuity isn't affiliated with any outside prep, and on its own practice test “your responses are not saved, scored, or reviewed.” So take it first.
What are the best free Casper prep options?
Start with Acuity's practice test and the 4 sample scenarios on its About Casper page. Acuity also suggests recording yourself on your laptop camera. For scored answers, each AI tool in the table above has a free tier.
Ours: sample video scenes, 20 sample questions and a library of 1,061 scenarios to read, all free with no sign-up.

Frequently asked questions
What is the best way to prepare for Casper?
Start with the official practice test in your Acuity Insights account, which Acuity recommends as the best way to prepare. You get it once you have booked your Casper test, and you can take it more than once. If you want your answers scored, which the official test doesn't do, try a free tier from a prep tool before you pay.
Is Casper prep worth paying for?
It is if you want feedback. Acuity's free practice test shows you the real format but doesn't score your answers. Prep with feedback scores each answer and shows what to change before test day, and most tools, Casper Prep by Confetto included, let you try it free first.
Is there a free Casper practice test?
Yes. Acuity's own full-length practice test comes free in your Acuity Insights account once you have booked your Casper test, and its About Casper page has 4 sample scenarios. CasperPractice.org, StudyCasper, CasperBooster and Caspermate also have free tiers.
Does Acuity's practice test give feedback?
No. Acuity says your practice responses are not saved, scored, or reviewed. To get your answers scored, use an AI tool's free tier. Recording yourself, as Acuity suggests, also helps you hear how you come across.
Is there an AI that grades Casper answers?
Yes, several, all independent of Acuity: CasperBooster, CasperPractice.org, Caspermate, Intervly, StudyCasper and Casper Prep by Confetto score typed or video answers. Confetto's 7-day free trial scores 3 scenarios in full.
Is this a review?
No. We did not sign up for any other service here, and we don't rate providers. Every fact about another provider comes from its own site, checked on October 17, 2026, with a link next to it.
