"took me way too long to start studying ngl. the mock exams on primarydiagnosticexam.com were the only reason i got comfortable with the pace, 300 questions in 5 hrs is brutal if you havent practiced it. passed, moving on with my life."

"honestly wasnt sure a question bank could help with something as broad as this exam but the mistake review function actually showed me i kept blowing physics questions on radiation production, not the imaging stuff i was scared of. fixed that in the last month and it made a real difference."

"did this in pgy4 while still trying to read everything, bad idea. switched to just grinding practice questions on this site for the last stretch instead of more textbook time and it actually stuck better. wasnt confident walking in but got the score i needed."
