I dont consider myself super smart, and here was my story.
I took the entrance exam last night, not bad at all.
Math: brush up on converting fractions to decimals, and vice versa. Learn military time, if you dont know it. Learn how many oz-pints-gallons ect. I got a 92%
Vocab: hardest section to me, and I suck at math, pretty sure the words were made up lol. Used a ton of medical terminology and made it very confusing, also did this section last, so I was tired. I got an 84%
Reading comprehension: stupid, time consuming but easy. I honestly just stared at the screen for like 2 minutes because none of the answers were that good. lol. I got a 98%
Grammar: Pretty easy. A lot of "which word is not grammatically correct" type stuff. A little bit of a headache, you just have to pay attention. I got a 100%
This was for the HESI-A2, just thought i'd share my story
