"passed basic knowledge and embryology both on first try. ngl i was skeptical about doing practice questions instead of just rereading manuals but the cryopreservation section on elsexam.com actually matched how the real exam thinks. wasnt flashy just worked."

"honestly put off studying for weeks, work schedule was brutal. what helped most was the mistake review after each quiz, it kept showing me i was weak on gamete prep and male rep physiology. didnt feel ready going in but it clicked during the actual test."

"just took the exam last week, passed. the mock sets on micromanipulation and embryo selection were close enough to real question logic that i stopped panicking halfway thru. quiet relief tbh, not gonna lie i almost didnt bother studying til the last month."
