Do you feel lonely or isolated? Are you missing home? Try to join a club or society, that will help you fit in more. Are you drinking too much, sleeping in and missing classes? Well, curb your drinking, get to bed early for a while, buy a good alarm clock and go to class.
What is you feel the subject isn't for you? Well with enough time behind you, only you could know.
However, if its simply a matter of the subject being hard, buckle down to it, you really need to make the most, learning is a skill, you need to learn how to do it.
