I was looking for sites when I couldn't solve a maths problem, then I looked for sites for courses and I saw Khan academy.The first thing you will see is that the interface of the site is very elegant. Then I installed its app and registered an account on it. There are almost every subjects and all chapters for every class. The chapters are taught by short youtube videos.
There are courses for commerce, science, test preperation, computing and many more. The videos are very helpful and you can even download them to watch later. The resources are very helpful and you can watch them anywhere. Khan academy is a non profit organisation and they get money from companies which invest in these courses . I recommend yout to try this site as the courses are free and there is no hidden cost. If you want to learn anything and want to understand any chapter, you can definitely try this!
