Hello, I'm an undergraduate student at Cairo University and I'm about to start studying Architecture this September. I really had no chance to choose to study Physics at an undergrad level. My question is whether it is possible in the US or in Europe to do a masters degree in physics without having a bachelor degree in it. Knowing I have always wanted to become a physicist and do research. I know that at least I should have some kind of background in quantum mechanics and other higher-level topics in physics if I want an MSc, so what is really the best I can do if I want to self-study Physics without affecting a degree much, noting that an architecture major is known to be really time-consuming.
