I was thinking of taking a 3 year course called computer system engineering technologist. What kind of jobs in Apple to do with Mac and iPhone could I get.
You need to have a Bachelor's degree minimum. An Associate's degree is from a 2 year college. And, I think, that a "Technologists" degree is a 3 year college. You need a Bachelor's from a 4 year college, though I think BS in Science or Engineering is now 5 years in many places.
