What are some good prep sites for the math and science portions? I took the official paper test and had: 24 Math, 24 Science, 36 Reading, 29 Grammar. I would like to try for an overall 30+ on my actual test. Please let me know!
I would suggest crackact.com. Probably the best site I've found for actual ACT materials. They have full ACT tests you can download and close to 100 tests to download for each specific section. It also comes with downloadable answer explanations to help you out when you get stuck.
If you're looking for sites to help you learn material rather than practice I would say Khan Academy and ACT Academy are good (although Khan Academy is definitely better for SAT). Also any of the ACT prep books from reputable companies are a good bet. They can teach you some test prep strategies to help out. Learning how to take the ACT effectively and new strategies can improve your score a lot even if you don't learn new concepts.
I’ve found PrepFactory to be very helpful. It is very engaging and not like a traditional practice test
