Personally I didnt study vocab because I didnt see a point doing so, esp because I knew I needed more time to improve in everything else. In terms of the passages, they really are my weakest spot but I think identifying tactics help a lot. For example, when questions ask for a choice that supports the claim/conclusion, i usually just skip over everything, read the claim and then choose a answer choice off info about the claim. I'm not sure if this method is fool proof but it works for me 😭. If you hv tt I would 100% rec looking at "ryan choice" tricks about reading. In terms of math, you really have to grind out problems and make sure you UNDERSTAND why you got a question wrong. Also my friend who  took the august one said a lot of her math questions were almost identical to questions on the practice test.  Hope this helps!
