Your ACT Math score can only get better with practice. Getting the score you want takes time and effort on your part, but hard work is usually rewarded on test day. Here are five problems similar to what you’ll encounter on the ACT. I hope you have a few minutes this weekend to find a quiet place and give them a try.
The numbering of the problems is meant to give you an idea of where in a section a problem might appear.
Answers appear at the end of the post. Full solutions can be found here.
