Hi guys,
I am planning on taking the ACT in Feb and was looking for the last minute prep. I came across this book called The Official Beginner’s Guide and it has the new updated practice test and a prediagnostic ACT test. I thought it was a great resource for the last-minute prep. It also has info about the new changes made to ACT exams. 
I am waiting for you to tell your result. 'Cause it sounds very risky to prepare at the last minute.
If we get relief from the coronavirus pandemic, the next ACT exam will be held on June 13. If anyone want a book for the next exam, I will recommend him to read ACT Prep Plus 2020. It provides expert strategies, online practice, and video tutorials. After studying it, one can get a higher score on the ACT. It is included with-
- 5-full length practice test with the answer explanation
- Analysis of 5 official ACT test
- Aditional online link to practice quizzes and videos
- Most popular questions and topics
