Looking to Brush Up on Calculus Before Jumping to Calculus 3

Asked by SunnyTraveler123
I've totally forgotten everything from Calculus 1 and 2. I'm considering diving into the 20 hours of videos on Free Code Camp, but I'm wondering if that's enough to prepare me for Calculus 3. Do you think I can just rely on those videos, or should I look for other resources?

For a solid review, you might want to check out Paul's Online Math Notes and PatrickJMT; they cover about 95% of what you need. The remaining 5% can be tackled with Professor Leonard's videos. These should help you a lot!

Just keep in mind, in school, you're juggling multiple classes and a busy life. If you focus, you can get through the calculus content fairly quickly. What do you need calculus for, anyway? Are you working on a physics engine or something?

Definitely try out Khan Academy's Calculus 1 section! Itโ€™s super user-friendly and has great explanations that could really reinforce your understanding before moving on to Calculus 3.

I remember 'that tutor guy' was really helpful! Not sure if heโ€™s still around, but his website guided me really well back when I studied this stuff in 2018.
