Khan Academy
A website/youtube channel that helps people learn/understand all kinds of things, ranging from math to history. Unfortunately the videos (I'm talking specifically about the math videos) tend to be long winded and the narrator takes 10 minutes to explain the simplest of concepts, really he comes across as some asshole who loves hearing his own voice
I have a final exam tomorrow, and I'm trying to watch a khan academy video to help me review but he just keeps yapping and won't get to the fucking point already
