Which books should I consider with my current skills? (Aiming for a 36)

Hey,

I have my ACT in April. Currently, I also have my junior year final exams to worry about, I’ll be free by 21st March. I have given the SAT before and scored 2100. I do crackact.com ACT practice tests whenever I have some free time. I am planning to do at least 15 after my exams end before the actual exam.

My math and science grades are quite consistent in the 33-34+ range but my reading scores fall short to around 30-31. I had the exact same problem in SAT as well, had scored 800 in maths and 700 in writing but reading fell short.

I only practice from crackact.com currently, I have ordered the red book. What other books should I be looking at? Do I have a decent chance of getting a good score considering the short amount of time I have left for prep?

Thanks
