IB Math Standard Level (SL) and IB Math Higher Level (HL) are two of the toughest classes in the IB Diploma Programme curriculum, so it's no surprise if you need a little extra help in either class.

**In this article, we've compiled 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.

## 2020 IB Changes Due to COVID-19

Because of the COVID-19 (coronavirus) pandemic, IB exams for May 2020 have been canceled and coursework deadlines have been extended for schools that have closed. Stay up to date with the latest information on what this means for IB diplomas, course credit for IB classes, and more with our IB COVID-19 FAQ article.

## How to Use This IB Math Guide

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

I split the following material up 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 Subjects:**Shorter summaries of specific subjects within a topic

**Videos:**Demonstration videos of how to solve past paper problems related to the subject

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

IB Mathematics SL/HL covers a lot of material. With so much material, you can't afford to fall behind because you won't be able to catch up. You'll need to master the subjects during the school year in order to excel on the IB Math SL/HL papers.

Common errors that IB Math students make include the following:

**Ignoring the material you don't understand:**If you didn't understand it from your teacher, then you need to look for outside help. This IB Math study guide is a great start, but you may 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 few weeks (that's why these courses are spread out over a couple of years!). This is why it's so important that you 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.
