ABOUT THE TEAS TEST

i dont have any degree yet i just finished my pre-reqs last fall.
i got a B in english 101
A in anatomy and physiology
and B in micro...

im concern about the reading and science
because for example there are alot of things to remember in anatomy and physiology alone... i just feel like i dont know what topic to focus on.
and for reading, im just worried if i dont have enough time to read the passage and answer the qs. to the best of my ability!

over all i think im a pretty average student. i study hard to get the grade that i want! last time i took a test similar to this was back in high school... and i passed everything i needed to pass, im just a little nervous for this one.
