How Can I Improve My Low ACT Score Fast?

Alright so I never studied for the act and I took a practice test recently and I scored a 20. :frowning:
Here’s the breakdown:
English: 21
Mathematics: 17
Reading: 20
Science: 20

Composite: 20

My goal is at least a 26 (preferably a 30) (by June 10th)
I’m taking the ACT June 10th for the first time (i have like 2 months to study for), and I need help. What are some good websites? I’m really slow, I don’t finish on time also. What are some good websites to learn the act grammar rules?

If i don’t get the score I like on June 10th, I still have tests on September and October.

There are some free test prep videos from kaplan, I think, on youtube. I watched one of them and thought it was pretty good. Do lots of practice tests. Take books out from the library so you don’t have to spend $300 on books (this way you can use the prior year books, numerous publishers, etc), and put a timer in front of you so you can gauge it. I would also recommend focusing on one section at a time for a couple of days each, like do one math test per day for 5 days and go over the answers. It may stick with you better. Good luck.

Take a section each day. Correct your mistakes. UNDERSTAND your mistakes and categorize the question.
