I’m taking the ACT in December and am wondering which books I should get. Thanks for any recommendations 
Buy the official test prep book…black book…any Barron’s or Princeton book (doesn’t matter for English, Math and science as to from where you prepare but for reading you will need solid timing strategies…prepscholar’ blogs are good)…if you need more practice 5lb book is good
Official is the one to buy. Everything else is a waste imo.
