Physics is very respectable. Takes a lot of work however - I just entered my first class of the semester today, which happened to be that subject. It's looking to be one of my hardest thus far, at least I'm expecting.
I'm in my third year of college, but my first year I came in as an informal Computer Science major. I was undeclared, but my courses were centered around the subject. Lots of tedious, almost boring work. Had to leave it... it was a great class I took though, real challenging (I was at Bryant University in RI). Swapped out of that school however, transferring to UMass Amherst. I have to admit I transferred because of the intense BOREDOM. Amherst is amazing - I'm having an awesome time over here.
College is what you make of it man. The vast majority of full time college students spend 4 years in college, if not 2. It is, IMO, one of the best times of your life. Duuuuu Itttt
