HESI help!!!

I'm feeling really down..I failed my psych HESI pretty badly last week, this week I got an 824/82% on my med surg HESI (technically failed because we need a 78% AND 850). When I study for my HESI I do 100 practice questions each night for about a week, I read the green HESI book and look through the purple Sanders NCLEX book. I now have to retake the HESIs on top of 5 other exams...I was hoping someone would have some study guides, ideas on how to study or anything! I can't really redo the same practice questions because once I see them I memorize the answer!

PLEASE HELP ME!

Use the Hesi book, only ....and study the wrong answers, too. When you see a question like this one:

What color of light do you stop at?

A Red

B Yellow

C Green

...also think about what you do when you come to a green light or a yellow light. Think about what type of vehicle you may be in. Think about why that traffic signal might have been placed there to start out with, etc. Expand on the practice questions in your mind, in other words.
