Would you prefer books or videos that go straight to the point. Books can get boring to read and sometimes the major points and things you should take note of are hidden in between too many unnecessary sentences that you miss them. But if you are the type that like reading and you are good reader, books can be good for you. But I still feel that you should have and request for some videos that you could watch as well to summarise the knowledge. The benefit of these videos is that you can always rewatch them easily than looking for a paragraph in a big book.
