Taking the TEAS test in 7 days and i am nervous any tips please?

[lovenurses2016]

Ok so I am planning on taking the TEAS test in about 7 days. I just got notified yesterday and I have been calling the school for quite some time and now and just got this word yesterday. I am so mad and upset because I like to prepare myself at least one month ahead of time but i don't know what i am going to do with myself because this TEAS test i heard it's harder than the Hesi. So i just started studying yesterday and i am so stressed right now. I also don't have a book yet since I can't afford to buy the book right now:(. I have been taking online practice tests and watching youtube videos. Math and Science are my weakness points so i am focusing on that for this next couple of days. I am really considering just not taking it but then again i just want to take it to see how I do. The school that I want to go to is a trade school(military paying for my school) and they told me that they will pick the top 16 people with highest scores so i feel so sad and stressed right now:(. Anyways, can you guys give me some tips and your experience when you took the TEAS pls...Thank you guys
