I'm sorry you're having trouble with studying and stuff. It's rough. Especially at your age (I don't mean to sound patronizing I swear! I remember being 18 and hating school and being absolutely rubbish at it).

On the one hand, you're close to the finish line. On the other hand, you're in a program you don't like - because of your parents. That's a struggle as old as time - our parents wanting one thing for us, and we usually want something else.
Ultimately, it's up to you to decide what you want to do. But the question is - What DO you want to do? Study? Do as a career?
