OK, I think first of all you should calm down. 5 weeks is a long time. You could start over with your studying and still have plenty of time. I wish I had some glorious piece of advice but all I can really tell you to do is study hard.
I didn't look much at First Aid until the last 2 weeks but then that's almost all I did read for those 2 weeks. I would read it once and make a mark every time there was something I wasn't 100% on. First time through I had marks at 75% percent of all the keywords (the words in bold on the left). Then I went through again and when there was something I still didn't get I would give it a second mark. Then I would go through it again and again..... You get the picture. I kept making bets with myself about which keyword would survive the longest. It was a tight battle between one of the cancer drugs and that chart with sphingomyelin and the gangliosides. They both lasted 11 circulations, I think!
Anyway, I really used my competitive/anal streak. I would high five my imaginary friends when I scored a good qbank %age. Dumb stuff like that.
Good luck.
ps. I thought qbank was much harder than the actual test. I got 74% right after all the questions, no repeats, but I waited till the last month to do my q's. DOn't forget you have lots of time! You could take a week off and still have a month left!
