"put off studying till like two weeks before. the instrument section on osaexam.com saved me, kept mixing up the different forceps and hooks and their practice sets drilled it in. passed first try, still surprised."

"honestly wasnt sure a website could actually help with aseptic technique since so much of it is muscle memory from the OR, but going thru their mistake review after each quiz showed me where my gaps actually were. definately helped more than just rereading notes."

"did the mock exams a few times, timing was the real issue for me not the content. got comfortable with the pace and that was it, passed with room to spare."
