Two ways to navigate this site

Navigate as you learn each unit

1. Content: these are the essential notes for each concept of the topic. If the note doesn't make sense to you, you probably weren't in class or weren't paying attention! Anyway, look back at your note or use the keyword in the title to search for an explanation. Once you think you got it, click on the "Related question" button to see if you really got it

2. Question: these practices will give you typical questions about the topic. You will receive instant feedback (nice!)

Whether you got the incorrect answer or struggle to solve the question, please watch the explanation video to see how you will approach such a problem. You may also want to click on the "Related content" button to revisit the concept 

3. Quiz: this gives you timed practice. The IB exam tends to give less than 1.5 minutes per mark, thus you can have an idea whether you are solving the problem too slowly or just right.
