What is the best way to self study? Watch
Ultimately, try to identify what learning approach is better for you. For example, if you learn things quicker by watching a video and hearing somebody talking about what you should learn, then the best learning approach would be visual. On the other hand, if you find yourself learning quicker by reading stuff from a book, just get the books regarding the topics/ subjects you need to study. In general, if you can’t understand something, try to look up multiple resources that explain that specific concept until you fully grasp it.
