CasperCoach

In March 2025, I built CasperCoach, A platform for CASPer test prep, while in high school.

CasperCoach helps pre-med, and other professional school applicants prepare for the CASPer through realistic Casper practice tests and practice questions, AI-generated practice scenarios, expert-written response frameworks, and in-depth guides covering every part of the test.

For background CASPer stands for Computer-Based Assessment for Sampling Personal Characteristics, and it's a situational judgment test used by over 500 medical, dental, and health professional programs.

It was created to kind of test them on more 'personality' based areas like ethics, empathy, communication, and professionalism, and it's become one of the most important non-academic factors when it comes to the actual admissions decisions.

I personally built CasperCoach because I personally had to take the test for my application to Western Engineering, and here is that story:

In late January I had to take the test, and when looking at ways to learn more and practice for it I only really saw 2 types of resources:

1. Random youtube videos about how the test works, and peoples experience
2. Different courses sitting behind +$200 paywalls for their 'indepth-guides'

None of which actually help practice, but only rather teach their self-proclaimed optimised frameworks.

Now none of this was actually that helpful.

The YouTube videos were surface level at best, and the courses were charging hundreds of dollars to basically tell you "be empathetic and structure your answer in 3 parts."

There was no real way to actually practice the test.

No scenarios that felt like the real thing, no way to write under timed pressure on prompts you hadn't seen before, no feedback loop.

So while studying for my own test, I started building the thing I wished existed.

AI-generated scenarios that actually matched the format and difficulty of the real test. A clean interface that mimicked the actual testing environment so practice felt like the real thing.

Guides that didn't just tell you what to do, but showed you why certain response patterns worked and others tanked your score.

I shipped the first version, used it for my own prep, took my CASPer, and then realized other applicants were dealing with the exact same gap I'd just spent weeks solving for myself. So I kept building, and eventually launched the platform publicly at caspercoach.org

To actually get users I wanted to start more so with organic content.

Every single day I would long, in-depth CASPer guides on Reddit, dropping the link at the bottom for anyone who wanted to actually practice what they'd just read.

Writing these posts took pretty long, since I focused on actually providing value and writing it in a way that's built more to go viral to gain credibility.

These reddit posts would often get 10-50k views per post:

From there growth took off and quite quickly I reached a few hundred users that signed-up and started practice.

About 4-months later in august I hit 1000 users

Now over a year later I have scaled this to several thousands of users, and helps of students out with their test :)
