## CasperPractice

CasperPractice is a specialist study platform for the CASPer situational judgment test, the open-response admissions assessment created at McMaster University and used by hundreds of health-science programs. Instead of generic chatbot feedback, the product runs a dedicated scoring model trained on a large corpus of real candidate answers, so responses are graded against the scale evaluators actually use and placed in a quartile band.

The workflow mirrors test day closely. You open a scenario, watch or read it once, and the timer starts; you then type or record a video answer exactly as you would in a live sitting. Within seconds you receive a quartile ranking, notes on specific sentences, and a rewritten version of your answer that demonstrates the reasoning a top-quartile response would show. A practice-test mode groups scenarios into full-length simulations so you can rehearse stamina and pacing, not just individual questions.

The library is broad — every major scenario type is represented, including ethics, empathy, collaboration, resilience, personal experience and media-based prompts. Progress accumulates across attempts, which makes it easy to spot recurring weaknesses such as one-sided arguments or unsupported claims. Free users can try the questions with limited AI coaching, while the paid Pro plan unlocks unlimited scoring and the 4th quartile guarantee, subject to stated conditions like answering a minimum number of questions with the same email used for the real test.

**Pricing & Plans:** Freemium. A free tier gives access to practice questions with limited AI coaching (the first attempts are coached at no cost), while the Pro plan is a paid subscription that unlocks unlimited scored attempts and the 4th quartile money-back guarantee. Pricing is discounted periodically on the site.

- **Realistic question bank and full mock tests:** Work through hundreds of typed, video and media-based scenarios, or take complete simulations that reproduce the CASPer sections, question order and per-question time limits.
- **Purpose-built AI scorer:** Answers are graded by a model calibrated on a large set of real CASPer responses, returning a quartile estimate rather than vague encouragement, plus sentence-level notes on what weakened the answer.
- **Instant answer rewrite:** After each attempt you get a stronger version of your own response, showing how to hold competing perspectives and land on a clear position without sounding rehearsed.
- **Competency coverage tracking:** Attempts are mapped to the competencies CASPer measures, so you can see whether ethics, communication or collaboration is dragging your average down and drill the weakest one.
- **4th quartile guarantee on Pro:** Pro subscribers who meet the conditions (minimum answered questions, matching email, official results forwarded in time) are refunded or keep lifetime access if they miss the top quartile.

**Strengths:** Purpose-built scoring model rather than a generic chatbot prompt; Quartile ranking and rewrites give concrete, comparable feedback; Full-length simulations mirror the real sections and time limits; Bonus: large free question set and a money-back guarantee on the paid plan

**Limitations:** Value depends on the accuracy of third-party AI scores, which only the official provider can truly validate; The free tier's coaching is limited, so meaningful practice volume requires a paid plan; Video-response practice still cannot replicate the pressure of a live proctored sitting
