What should I do now that I can't study in the current course to lack of funding

Hello,

I completed my O level exams in 2006 from Bangladesh and my A level exams in 2009 from the UK with A's in all the subjects. Then I enrolled at Imperial College London on the BSc physics program. I completed my second year in 2011 and then I faced a financial problem, so I spoke with my department head and was allowed to interrupt my studies for one year.

Now, I am supposed to go back to the UK in October for my final year, but since I haven't managed my tuition fee, I have decided to withdraw from the course.

Now, I am looking into opportunities in the USA and Canada to either transfer to another university or to begin a new course altogether.

I would be grateful if you could suggest whether I should drop the subject entirely (i.e. not think of transferring) or start out fresh in another course.
