Khan Academy

I use their courses for every thing I wish to learn, every time before I start learning a new concept either in math or on the web, I check a course here. It helps you guide your mind on the right track. Of course, it cannot replace a university all by its own and for that you need to actually attend courses and be supervised by a teacher/lecturer. But for me, starting something new is the hardest part and Khan academy help me in that regard.

Not learning anything from this. The creator needs to learn how to talk. It's always "Sal meant this" or "Sal meant that" maybe instead of doing one problem for 10 minutes in a video, how about you just tell me the formula so I can do just not that one problem.

I have used Khan for science courses including biology, chemistry, and anatomy and physiology on the university level and am very satisfied with the layout and length of the videos and problems. My kids use it as their primary source of math education as homeschoolers. Sequential learning experiences for FREE to anyone are provided for learning of many subjects. Khan Academy focuses on understanding requiring few problems, but mastery which I prefer over multiple problems of "busy work." There is also an option to "test out" of material already mastered. We find the site exceedingly helpful.

Khan Academy is terrible. Khan gives a complcated formula, which is fine, but Khan poorly or does not define what each variable—of several—means. Complicated formulae are easy, just plug in; but one has to say what each variable stands for. Khan is much too minimalistic, where one is puzzled how F01 is derived, "add all the scores," or "input the greatetst score," or, "average the scores." Instead, there is no defining the variables. Khan is ridiculous. Khan is no help for the SAT, for instance, because Khan is is trying to say in one sentence what requires six sentences.

I had been doing khan academy for a while when it restarted all my progress. I summited a problem to customer survive but it has been a week now and I have heard nothing from them. It is very frustrating.
Besides that khan academy it a good teaching app.

Khan is said to teach math, they do give math problems and videos yet they don't explain it that well, and its not "fun" or in other words, we kids don't really want to play on it due to it being just math and nothing else, no fun! I would not recommend this for people who like fun in education but I would for those who just want to study study study and have there mind just set on the one task: master this skill. 3/5,1 point for encouragement and the other point for explaining.
