I took the TABE test yesterday for La Puente adult school for their LVN course. Let me say it was really easy. Even though it was timed test; I didn't have a problem with it at all. Especially with the reading portion, if I didn't know the answer by skimming over the answer key I just moved onto the next problem, and came back to it when I had time.
Math was simply just addition, subtraction, multiplication, and division. Know your fractions, percentages, and decimal points! There were a few geometry questions, maybe 2-3 at max. One of them was finding the circumference of the circle. There weren't any word problems from what I can recall.
Reading, it was pretty much straight forward. Some of the passages were long but as long can read fast / skim you should be okay.
Spelling, one of my worse subjects back in the day. The correct answer stuck out like a sore thumb. My suggestion is to write out the word on your scratch paper and then choose your answer. I remember one word that I stumbled on, Breviary.
I scored 12.9 on 4 of the tests and 12.4 on the other one. Make sure you double check your answers if you have spare time. Well, time to start studying my anatomy and physiology!
