I apologize in advance. I get that people study differently, and you are more than welcome to request a study group.
BUT, I would want to punch myself and whoever I was group studying radbio with, in the eye, if I had to care what other people thought about my answers in radbio.
It's a MCQ exam. IMO, there is minimal need to talk it out. However, I wish you best of luck with finding a study group for it.
