Your teacher know more than you do.S1 P4

Actually it is the reality that we all hate asking doubts (literally not all). But teachers should be knowing more about the subject than us because of-course they are elder than us and secondly they are in this field of studies for an period lot more than we do.
Asking teachers could make many things clear, though you cannot get all of your cleared, they can guide us to get the correct solution.
Apart from asking teachers, it is fine if you know someone who was really working in that field or does have some knowledge about it and probably willing to teach you.
