Kijavátanátok az angol házimat? Ha valahol hibás a mondat, légyszi indokoljátok is meg, miért!?

I would like to work as a doctor, because I want to help sick people. At the moment I don't know what kind of doctor I want to be. Perhaps I'd like to be a toothdoctor. Doctors must to wake up early and must to work a lot of and faithfully. They have to be patient, kind, clever and experienced. I learn chemistry and biology in bigger classnumber to admit to an university. After the final exam I'm going to study Medicine at the Semmelweis University. I hope I will be a good doctor.
