how to study for the teas science portion in one week

hi everyone i’m taking my first attempt of the TEAS on Aug 3 and i’m really struggling with studying the science portion. i’m using the mometrix textbook and ive just been reading and creating flash cards along the way, but im honestly so overwhelmed.

i have not finished my A&P prerequisites yet and im very nervous because i am struggling to really retain the information i am reading. i reserved the science portion for this whole week, but i dont know how i am supposed to do well if i can barely focus on all this information. please let me know if you have any tips on how to study for this section effectively! being overwhelmed just makes me so unmotivated😣
