tip #1 - start studying early! (no i didn't actually follow this one but wish i had)
tip #2 - make a study guide for yourself
tip #3 - talk to students who've done it before at your school
tip #4 - if you don't know the answer then show them what you do know and how you would use that to think it through
i studied all day every day for 2 weeks. used class slides, notes, and textbooks, and went to audiology online when i still had questions. i studied the expected things and also the less expected things, and that seemed to help. even after all that i still felt unprepared. i thought the oral comps were easier than the written comps.
