If you don’t know, Khan Academy is a free online educational website that consists of an amazing set of videos (over 3000) made by the amazing, Salman Khan.  Khan uses a Wacom type of tablet and a headset to make videos to teach a variety of subjects. Khan Academy is mostly known for Khan’s mathematics and science videos but he also covers economics, art, history and more.  Khan has made hundreds of videos for math including ones covering about every subject imaginable in algebra. The best thing about Khan Academy is that not only are there thousands of videos on multiple topics, but they are taught extremely well; he is definitely the teacher you dream of having in college. Khan explains more than just how to do problems, but actually gives you the intuition behind them.  Khan Academy can be very a handy reource, and here are three good reasons to use it.


If you finished your high school math requirements during your junior year of high school and then you decided to not take math your freshman year of college, then the chances are you have forgotten everything about math. So, before you go back into calculus after not thinking about math for three years it might be wise to review a bit. Once you watch a couple of videos you’ll probably get a sense of how behind you are and can then go from there.


Khan Academy is also a good resource when you are currently enrolled in a class. Books in general can be annoying and difficult to learn from, especially with subjects like math and science. Khan has most likely made a video on the subject you are struggling with and can help you with that upcoming quiz.

Test out of Classes:

If you were not an amazing high school student and did not take calculus, but have decided you want to in college, you have a long and slow ladder to climb. You can only take one math class at a time, and if you only took algebra in high school, it’s going to take you a while to catch up. However, there is a solution. Most colleges will allow you to “test out of” or actually test into a certain class instead of taking all the prerequisites. So, if you think you could test out of trigonometry or whatever class you’re missing, you can use Khan Academy to do so.  During the summer, you could watch all of the Khan Academy videos on that subject, and try to test out.
