# ACT Math Gauntlet

Can you make it through the ACT Math Gauntlet? 🙂

I’ve created a packet of 187 practice ACT Math questions that cover every topic that you need to master for ACT Math success. If you can make it through the Gauntlet, and if you understand every problem and the strategies, concepts, and formulas needed to solve them, you should be all set for a high ACT Math score.

The answer key is at the end of the packet, but if you want full video solutions and explanations for all these problem, strategies for tackling ACT Math problems, and an ACT Math Facts & Formulas cheat sheet, check out the ACT Math Bootcamp.

For question no. 111, shouldn’t the answer be D. The answer sheet states E as the correct answer, but both -3 and 7 satisfy.

When you plug -3 back in to the problem, it gives you sides lengths of -4 and -12. Side lengths can only be positive. So -3 “works” mathematically, but not in reality.
