perfect (4th quartile) casper score here.
There is no way to prompt chatGPT and have it reply and give a good answer in the time allotted for each question.
And then it'd become obvious that you didn't know what you were doing for the recorded section.
The casper was ALMOST a good test, it just was so time restrictive that if you can't type at 120+ WPM you basically can't give thoughtful answers to the written portion. And you just don't have time to think for the recorded portion.
I will say that the recorded portion of casper, despite being way too time strict, is a GREAT practice for any school that does MMI's. I found several opportunities where having done the casper was a huge boon in interviews.
