Even going to the mundane and common sense – what is better learning alone things you do not understand or having someone who understand the topic? If I going to give you book on physics or math even for beginner you would have much more problems and trouble then person who have someone who is more advanced and have better understanding (better and PROPER) so you have a lot of clarity moments which it not necessary to be like that when doing things alone without any ideas what those things are about of having assumptions about them of how they are like :)
