How to Refresh Your Math Skills For College: 3 Steps

Refreshing your math skills before college can make your academic journey easier. Instead of taking prerequisite math courses in your freshman year, you can plan ahead and familiarize yourself with core math skills. Here are three steps you can take to make quick improvements in your math abilities. 

1. Understand College Math Requirements

According to university systems such as the University of California, it’s recommended that prospective students take at least three years of mathematics. This generally includes algebra, geometry, and pre-calculus. Of course, you most likely do not need to brush up on all of these subjects, just the ones relevant to your major.

2. Take a Math Refresher Course

Once you have identified which math courses are the most important for your area of study, you should enroll in a math refresher course. A math refresher course is one of the best ways to improve your math skills because you learn in a structured format and potentially earn credit towards your degree. 

Preparing for AP Exams?

layer edX offers free courses to help you prepare for your next AP exam.

3. Test Yourself

When it comes to improving your math skills, practice makes perfect. According to research reported by Scientific American, it’s been shown that frequent testing (when done right) can improve learning. Several free online resources offer free tests and practice questions that you can take to identify gaps in your math skills.
