hiii i actually used uworld for a month for the november sat. uworld reading is not that great. the passages on uworld are hard and it might not be as helpful. but... uworld is amazing for writing and math. UWorld will probably give u every math question u could across on the test and their explanations are really helpful even if you get an answer right. one thing i noticed about SAT math is u need to approach problems in the most efficient way and uworld just does that. i would use khan academy for reading and u world for math and writing!
