(Note: If any videos are taking more than a few seconds to load, copy and paste in another browser! Videos sometimes take a long time to load in Google Chrome for Unit 3+4)

These blocks include solved problems.

A Level UP problem set includes:

Level 1: Class level problem: introduction to a concept with a simple problem

Level 2: Homework level problem: more in-depth, longer problem than Level 1 that is meant to thoroughly address one concept

Level 3: Exam level problem: a problem that requires some intuition and usually requires integrated knowledge of multiple concepts, shorter than Level 2 but requires more thinking
