tips for HESI test... help!

Which HESI? Entrance? Specialty? Exit exam?

Without knowing specifically which one, I can only say that you should go over what you know. I do know that the exit exam is somewhat similar to the NCLEX so if you're doing that exam, study for it like you'd study for the NCLEX or your exams. If you remember your final exams from each class, that would be a good place to start. The good news in all this is that the HESI isn't computer adaptive. I would suggest using test-taking strategies you'd use for the NCLEX on it just because how the test questions are written.

If it's an entry exam, again, go with what you know. I've never taken that one (TEAS here) but I imagine that you should go with what you know and review the prerequisite courses you've had as a good place to start. This specific exam shouldn't be written NCLEX style so it shouldn't be too bad. Tough, but not too bad.
