IB Math SL and IB Math HL are two of the toughest classes in the IB curriculum. It’s no surprise if you need a little extra help in either class.

**I’ve compiled this article of the best free online materials for IB Math SL/HL** so you can get all the IB Math notes you need in one place. For convenience, I ordered the resources following the IB Math SL/HL syllabus.

## How To Use This IB Math Guide

If you’re in search of information on one topic, **use the Command + F function on your computer to search this guide for that specific topic. **For instance, if you want to read about Algebraic Sequences, use Command + F to bring up the search function. Type “Algebraic Sequences,” and you’re computer will show you all of the study materials for Algebraic Sequences listed in this article.

I split the material into three categories:

**Broad Notes:**Longer (generally 3-10 pages) that provide an overview of most or all of the subjects covered in a topic.**Specific Subject:**Shorter summaries of specific subjects within a topic.**Video:**demonstration videos of how to solve past paper problems related to the subject.

## Common Study Errors IB Math SL/HL Students Make

IB Math SL/HL cover a lot of material. With so much material, you can’t afford to fall behind because you won’t be able to catch back up. You need to master the subjects during the school year in order to excel on the IB Math SL/HL papers. Common errors are:

**Ignoring the material you don’t understand.**If you didn’t understand it from your teacher, you need to look for outside help. This IB Math Study Guide is a good start, but you might need to supplement with outside tutoring, too.

**Only studying right before the IB Math SL/HL papers.**As I said before, there are too many topics for both courses to master in only a couple weeks (that’s why these courses are spread over a couple years). Master the subjects when you’re learning them in class! If you're still struggling, this guide can help...but don't be afraid to get tutoring from a teacher or other expert.

## Summary: The Best IB Math Study Materials

IB Math has six core topics that both SL and HL students study, as well as one of four options that HL students will also study. There are many free IB Math notes and study resources available online, especially when compared to other IB classes, which often have few high-quality online resources. **This makes it easier to keep up with what you're learning in IB Math and be prepared for all the exams for the class.**

There are multiple types of IB Math study resources, including general study guides, in-depth notes, and videos you can watch. Try out each of them to see which ones work best with your study style. Remember, you want to study **early and consistently** in order to be well prepared throughout the school year.
