I have been offered masters in petroleum engineering (1.5 years course) for february 2014 intake. I had opted for masters in engineering science petroleum engg, the 2 years course, but the university said they don't directly offer the course to international students, instead I need to complete the 1.5 years with 65% in all units. So how difficult is this ? So if I take 1.5 years program now, can I switch over to the 2 years one later, if yes is it easy and are there any other criteria? If i take the 1.5 years program will i be able to stay back and work at Australia.
