Free knowledge! What more could you ask for? – Khan Academy Review

This will quench your thirst for knowledge! This app is absolutely incredible for ALL ages. Each subject has extensive modules with valuable content, delivered in comprehensive and comprehensible ways, in small digestible time blocks. If you're curious about anything from preschool math to macroeconomics, human anatomy to astronomy, engineering to entrepreneurship, grammar to art history, etc- THIS is your answer source. I'd recommend this to anyone and everyone from preschool age to 105. There's even test prep for SAT, MCAT, NCLEX-RN and more! And Sal Khan is unimaginably enjoyable to listen to. This is a must have app!
