It's possible to score well on the teas test if you generally retained most of your knowledge in converting percentages and beginning algebra. in the reading section, you'll find that you'll have to interpret passages and understand fully what is being said, in order to answer questions correctly.

. Sciences have the longest time amount given (55min.) and is usually difficult for some students. Know your chemistry i.e. acids and bases, know the difference between energy, i.e. kinetic vs. potential, also know basic biology: taxonomy, i.e. phylum kingdoms, species, etc.. and of course anatomy and physio stuff.. some micro. It's definitely doable, but keep in mind if you're just studying now for this TEAS V (not IV) it is totally different and harder. People spend at least a month in preparation for this test to just be in the 80th percentile.
sidenote** I know you mentioned you had no choice, but just in case you didn't know, some schools only accept two attempts at the TEAS test. So if you already took one, you might want to consider in these next five days if rushing this test or waiting out a year and studying for it and getting a better score is right for you. hope this helped.
