am i stressing out to much?
Yep.
But i'm one to talk, I have only had 4 hours sleep in 3 days trying to prepare for our Acid-Base Balance, Fluid & Electrolytes exam.
Coming up with easy ways to remember stuff is great. Think SAMPLE history. You know SAMPLE all you have to do is follow the letters and you got your assessment.
Or pick up on little parts of the word. How I remembered that cations are positive is the small "t" in cation looks like a (+). Or, as silly as it is, Acidosis is a CNS depressant because there is a "D" in acidosis and depressant starts with one. Or, "Dead people don't breath" is how I remembered in Alkalosis your RR & CO2 are low, and your least likely to survive getting alkaline.
Ok...so see...make stuff up that will trigger your memory at test time.
Take breaks. Lots of them if you have to. My study partner and I took breaks almost every half hour. He would go play a round of Halo and I'd play on POGO. Or if we were at the park, we'd go walk down to the water and throw rocks in or kick sand or watch people go by and I'd tell him "their story" while he looked at me like I just grew a third head. Just screw around for a bit. Something non test related.
And on test day....try as hard as you can not to cram all day. Just study regularly and on test day review key points. By then either you know it or you don't.
When you go to take the test, take a deep breath. Read it and try to answer it without looking at the choices. If your answer is there, then VIOLA you knew it. If not, then work through it.
