When someone prefer to study alone, on his own, without school, I am tempted to use "self-student". But this word apparently doesnt exist.
Is there better way how to express this in one word?
EDIT
I wish to express that someone is good self-student. For example "Peter is a good self-student"

Perhaps you are thinking of an "autodidact: a self-taught person."
