I'm writing my test today. Here's what I did to study for CASPer:
1) Read "Doing Right" by Philip C. Hébert - Excellent crash course in medical ethics in Ontario, the book contains a lot of different scenarios that you shouldn't just read through and gloss over, but actually think about and give yourself 3 or so minutes to write an answer. I bought a small kitchen timer for this purpose. Discussing cases with friends could be helpful, but I'd caution against it because CASPer is not an interview. Don't study as if it is one. This book can be hard to come by, make sure you buy/check it out in advance.
2) Look up the background/FAQs of CASPer - Get a very good understanding of the format of the test, use CASPer's sample test to your advantage (
https://takecasper.com/sample-casper-test/), learn the history and acknowledge that the test is designed so that it is difficult to improve your score by studying
3) Find sample questions from different websites and use those to your advantage. There's tons of stuff on YouTube if you do a quick search for 'CASPer sample questions', 'medical ethics questions', or 'medical interview questions'.
4) Go over your ABS shortly before test day. Make sure you are familiar with everything you've done. Possibly have that list read to /very/ quickly skim over if you blank during the test. Remember you can have resources beside you.
5) Practice taking notes for videos/sample questions to accurately get an idea of the scenario. On test day, you can't go back and re-watch the video. It's a 1-time deal. Make it count!
This last thing is just a note. I was a little surprised that this study found the median typing speed of medical residents/fellows was around 36 wpm (
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3963776/). There's a lot of bull**** out there about answering a question fully and approaching from multiple angles. Remember you have to write 3 questions in 5 minutes - that breaks down to 1 min 40 sec per question. Your responses will be about 100 words (more or less, I feel like the study might underestimate the skills of you beasts) if you're a fast typer. How much can you really fit in that space? Obviously use your discretion when you type and allocate time as you see fit, I just caution you to be careful. Don't bite off more than you can chew in your answer approach.
