What are some key differences and similarities between the SAT and the ACT? Are they worded/structured much differently, and is either easier than the other? Also, what are good score ranges needed to get into a top 100, top 50, and top 20 national university? I haven't taken either yet, though I did take a PSAT last year (sophomore year) but that score wasn't fantastic and I took it before I took Algebra 2 or advanced English. This year I will be retaking the PSAT with more knowledge on the topics asked. My last PSAT score was a 1260, which isn't great but will definitely be improved. Is there any other advice anyone could give me concerning these standardized tests?
