Try to cheer up; you're only missing the 77% by a few points, and those are possible to make up if you try.
I would suggest that you evaluate how it is you study. Is it usually alone? Try a study group. Is it usually in a group? Head to the quiet section of the library by yourself. Or, try a combination of both. I have found that using an NCLEX review book (one that has rationales for all answers-very important!!!) has been sooooo helpful. I use Saunders Comprehensive review, and I know alot of other people on this site have it and like it alot.
I also bought a $5 dry erase board and dragged my boyfriend away away from the X-Box :chuckle and into my office to quiz me on signs/symptoms, treatments, and the pathophysiology of whatever it is I had to study. My first test was a 74%. And I just found out this week that my second test was a 91%, with a class average of 82%.
I worked my butt off trying new methods of studying for this test, and it obviously worked. Try something different for your next test that you never have before, and hopefully you'll post a message that your hard work paid off. And if all else fails, post back any questions you have right here and we'll all be happy to answer them!
Good Luck on your next test!!! Don't give up!!!!!!!
