I scored a 33 on my School’s ACT (32 Math, 34 science, 30 English, 34 reading) with just a week of casual prep. I had prepared heavily for the SAT which I got a 1490 (770m / 720 rw). How difficult would it be to improve the 33 to a 35/36? It’s only 2 points, but I’m not sure if that’s actually way more difficult than it seems.
Your 33 is actually a 32.5 rounded up. In order to get a 34, you need 4 more points among any of the sections. In order to get a 35, you need 8 more points in any of the sections.
