Student results

From first scenario to acceptance letter.

“I started using QuartilePrep about two weeks before my Casper. What helped most was seeing where I was being too generic. Once I fixed that, my responses got a lot stronger.”

Priya S.

Accepted · McMaster MD

“The MMI circuit mode felt a lot closer to the real thing than anything else I tried. After doing 40-plus stations, interview day felt way less intimidating.”

James K.

Accepted · University of Toronto

“I needed prep for Casper, PREview, and MMI, and I really did not want to juggle three separate resources. Having everything in one place made it much easier.”

Aisha M.

Accepted · UCSF School of Medicine

“I honestly did not expect my Casper score to move that much in a week. The feedback was specific enough that I could actually see what I needed to change, and I ended up with Q4.”

Daniel R.

Accepted · PA School of Northwestern

“I was applying to programs that wanted both Casper and PREview, and at first I was treating them like the same exam. This made the difference really clear and helped me prep for each one properly.”

Common questions

Is QuartilePrep free to use?
Yes — several scenarios are available free with no account required. A lifetime access upgrade unlocks all 36 CASPer scenarios, full MMI stations, and all AAMC PREview modules.
How accurate is the AI quartile scoring for the CASPer test?
Our model is calibrated against Acuity Insights' published scoring rubrics and trained on thousands of rated responses. While no AI perfectly replicates human raters, users consistently report that our quartile estimates align well with their actual test scores.
Does this cover AAMC PREview prep?
Yes. The PREview module covers all 8 AAMC pre-professional competencies with situational judgment scenarios designed to match the format and difficulty of the real exam. Responses are scored against the same expert-consensus model AAMC uses.
How is MMI practice structured?
Each MMI station gives you 2 minutes to read a prompt, then 8 minutes to respond — mirroring the real MMI circuit used by 60+ medical, dental, and PA programs. The AI evaluates your response across empathy, ethical reasoning, communication, and critical thinking.
Which medical school admissions tests require CASPer vs. PREview vs. MMI?
CASPer is required by 200+ medical, nursing, and health professional programs in North America and is submitted through Acuity Insights. AAMC PREview is required by AAMC member MD programs and submitted through AMCAS. MMI is an in-person interview format — not a pre-application test — used by many Canadian and some US programs. Depending on your school list, you may need to prepare for all three.
