Question

will the video lectures be enough or do i really need to attend the online forum? because i cant.

Answer 1

In most cases the video lectures are enough, this forum is more for help when you get stuck and need a resource for help.

Answer 2

Usually, you can not absorb everything from a video lecture, unless you already know the topic in some advanced way, which is not usually the case.So, you need to study from a book and the forum here, is the finest place for your questions
