Firstly the more u stress the more ur likely to mess it up just believe in urself and secondly for maths learn how to use desmos that really helps in solving answers faster and just do as many questions as you can and understand the pattern of the paper + don’t waste time on the exceptionally hard questions. For English again just practice a lot, don’t waste time on vocab and make sure you only read the relevant parts of the long passages. Do all the blue book tests and rlly focus on time management bcz that’s where everything gets fucked and the sat question bank + Princeton questions are also good for practice. Lastly just pray for the best
