Absolutely amazing information

I love the way you present all of this information. I’m re learning it all 20x better than I ever did at school thanks to the way that you teach it. The diagrams and colours make it very easy to visualise what I’ve learned when thinking about it all a few hours later to solidify the information in my mind.
Also the quiz section at the end of each section are very thorough and well put together. Currently the only thing I would update is that when moving rays and lines around on some of the quiz sections (not all just some) the whole page moves as well as the line...this can get a bit frustrating...but absolutely love this and can’t wait to brush up on more of these fundamentals...I reckon once I have I’ll be delving into some of your more advanced topics, thanks so much! Ps your voice sounds like John Mayer at least 70% of the time you talk...and I mean identical, my g/f was next to me while studying and said...John Mayer can’t know all of this about Physics and Maths as well!?

Most underrated service out there!

I discovered Khan academy during my university studies and came to realise this site is completely free but AMAZING. It’s not a half arsed quickly put together app or website it’s a fully fledged lesson / course provider for FREE. I highly recommend using this app / website if you want to learn anything before paying for a service. What these guys and gals are doing at Khan academy is amazing! Always believed education should be free?? KHAN academy is your answer. And no I’m not sponsored/ work for them or anything I just really like the service. I started the maths one after finding during my science uni studies my maths was lacking dramatically thanks to Khan it made my course a whole lot more bearable. 100% download. I never leave reviews but this needed one!
