I am now studying Computer Application, a bachelor degree in India. I can get a job in the IT sector if I try only a little harder. But I have this deep desire to study Physics starting from undergraduate.

My high school science scores were average. I consider myself as a smart working science student. I want to apply in UK colleges as there I can start from bachelor degree even if I already have one. I study Physics whenever I get time apart from my present course preparation. But, I have this depressing and demeaning feeling within me that I shall not be able to cope up with Physics, I shall fail and that I don't belong to that field.

I want to know how can I be finally sure whether I have what it takes to study Physics. So that either I can finally remove this desire of Physics from my head and concentrate on Computer/IT jobs or prepare myself for another field of education that I think will best fit me. How can I assess myself?

It's private to me, so I don't want to ask anyone close to me. Not even my almost-a-physicist brother. I struggle a bit at solving deep thinking problems. I am slow at math but I don't give up. Often it makes me cry, but the next day I'm again after it. And I don't think I shall be happy in the IT sector.
