Nov 27, 2010 - Sal, I want to personally thank you for everything you are doing. You left a lucrative hedge fund job to teach the world and you have helped me and so many others with your videos. You are better than all my math professors I've ever had combined and you really help. Going to the core of the problem rather than me memorizing each step to get an answer. First paycheck I get after university I'm donating all of it to Khan Academy!

Mar 4, 2011 - I'm from sweden and I wish all my teachers where like you :(Every teacher I've had and has right now just (for some inexplicable reason) take for grantage that everyone have already done the course before and is ofc experts that just wants a repetition of the subject (!?!?!), especially in these hard math and psysics classes...Thank you for assuming that I'm a complete dumbass at this :D You're a GOOD teacher! I think I'm actually learning this O_oBtw: What program are you painting in?

Apr 21, 2011 - hey man, i just want to say thank you. posting up such helpful knowledge with the only benefit being teaching others is truly a great thing. you have significantly increased my understanding of all this material and i feel extremely confident for my finals. its upsetting that students pay institutions thousands of dollars for instruction worse than reading a book when there are true educators like yourself. thanks so much

Jun 14, 2011 - Thank you very much for this. It has and will be very useful in the test I have coming up. I think that the main difference between your method of teaching and other methods that I have experienced, is that you don't take any shortcuts (at least to my knowledge), so things are not misunderstood.

Jun 21, 2011 - I graduated a couple years ago and I'm watching these just for fun, because I like the subject and the awesome way you explain. Thanks!

Sep 10, 2011 - I really appreciate your doing this. My teacher tries, but he really is inapt at teaching this subject (or at least with teaching methods he uses). This, however, works like a charm. It turns what seems like a foriegn language to more of an adcanced english.

Jan 29, 2012 - The thing I like better about patrickjmt is that he talks faster and doesn't ramble as much. Also, I think khanacademy would be more efficient if he pre-wrote some of the things, and it just popped up like slides of a powerpoint. That way, it would be faster and he wouldn't spend as much time writing it and more time explaining.
