Any Nurses Out There Who Could Offer Some Help?

[Seniorstatus14]

Hey y'all, 

As some of y'all know, I just started my first semester of actual nursing school (3rd year of college, 1st semester of the professional nursing program). I'm struggling a lot right now and I'm really stressed out. I have 2 tests and a skills checkoff this week and 2 tests next week. All 5 major "tests" are in the span of 7 days. That's not really my main problem right now though. 

My final "test" of the testing period is actually a retest. It's a dosage calculations HESI exam. In my program you take a self-taught dosage online course and online medical terminology course. You get about 2 months to complete the two courses and then you have to take a HESI on the dosage one. You need an 80% conversion score to go to clinicals. I made a 73.66% conversion score on my first attempt. Part of me wants to say that I freaked myself out and panicked too much and that's why I didn't get the 80%. The other part knows I struggle with a few things (reconstitution problems, picking out what's important and what's not, etc) and I'm worried I'll screw up the second attempt. If I score less than an 80% on my second attempt I am essentially "kicked out" of the program until the fall semester. That would put me two more semesters behind. So I really need to pass the second attempt. They say everyone passes the second round, but I'm anxious. What if I'm that one person who fails? I don't think I'd be quite so nervous if I didn't have so many other assessments in between now and that second test. 

If any of you current nurses have any tips on how to tackle a HESI, or how to pick out what is and isn't important, or even if you know of some great websites with practice questions (I'm running out of good sites :/) please let me know!! Or if anyone in general is reading this and has some great testing anxiety/regular anxiety tips I'd love to hear them. I have felt sick to my stomach for a solid week now and lots of bad headaches and I know I'm not sick. It's just the stress and anxiety of all this coming up at once. Plus we have hospital orientations and stuff after class this week and it's just a lot.
