After having read a big part of "Who wants to be a Physicist" I was quite surprised that it is possible to apply for a Ph.D. with "only" a Bs.Sc. It is the same here in Argentina so now I'm guessing that Argentina took US example. I'm currently finishing the first year of University and the "Bachelor of Physics" lasts 5 years minimum. (The last year and a half consists of a specialization by doing research to help a teacher or something like that. It can lasts of course more than a year.) If I'm not wrong it is not written in "Who wants to be a Physicist" how many years does the Bs.Sc. lasts in the US. I had a feeling of like it lasts 5 years which really surprises me. I thought it was 3 years. But I'm not sure though. Can you tell me?
