Your science and math GPA makes up 40% of your points to get in! With all A’s, you’re at a huge advantage. Honestly, the English section has the lowest weight in your overall TEAS score and (I believe) the least amount of questions. Focus heavy on studying your science and reading. Try to be solid on basic algebra. If you can get comfortable with grammar rules, prefixes, and the parts of a sentence then you should do well on the English section. I’d recommend getting a book to study with practice tests if you don’t already have one 🙂 I’m sure you’ll do awesome!
And from what I know, they do not take into account if you’ve taken the prerequisites with them or elsewhere. You just have to have everything completed. The majority of the people that have gotten in took everything except for BST and ILR (if they didn’t just test out) at other colleges.
