I follow a couple of managerial and business, SME types, courses here. It contains valuable information; nothing so major or "secret" but it is always good to know that the things you do are confirmed by other people or experts throughout the world. I love the confidence and confirmation that comes after watching each course. II would go for a 4-star, but Khan Academy is giving away a lot for very small help and attention in return. I love it so a 5-star it is.See positive reviews
Khan Academy could be a very helpful website if we could tweak a few things. First, once a person mastered a skill it should STAY mastered. I would suggest teaching the subject before you try to do it and take kids averages down. And DUMP AND DITCH Sal!!!!!! He has a lazy way of talking that is hard for kids to pay attention too him and his handwriting could use improvement. This was NOT intended to be mean review but SERIOUSLY MAN no one wants to listen to you talk for 10 hours!!!!!!!See critical reviews
It is not a solution designed for exams. Exam preparation is a whole different world. You need to consider that at Khan academy the information is not arranged in a way to fulfill all the criteria in SAT. It is helpful to illustrate some baffling points, especially in math, but one must not limit one's self to the content of Khan Academy.
There is an old adage in education , that 'Spaced' learning is more effective than 'Clumped' learning. Waiting for the next Mastery challenge teaches patience, allows you to practice more skills in the dashboard, so the mastery challenges have more to do assessment on, and as you note, ensure that the concepts are transferring from short-term, to long term memory in your brain.
