Please share their method, this help a lot of people

Hello I'm physics, at present I am graduate student, my performance is very low, I believe that the fail is the method of study, can help me to improve my performance, please telling me how you study physics, what methods you use?, how you prepare an exam? Thanks

I can construct a basis depent of basis non-orthogonal, how might make up? and what happen with the eigenvalues and elements of the operator. someone know if the situation present in some quantum system.

which are the consequence of choice a basis non-orthogonal?

Hi, is possible make up a operator in a non-orthogonal basis, if is possible how I can contruct the operator. thanks
