Well, that's what I did, and not to blow my own trumpet, but I did quiet well. But like I said, skill, and tallent are big factors, some people work less and do better, others run themselves into the ground and get no where.
As far as I can remember [although the system has changed since] there are about 5 subjects in 1st year, dealing with introduction to structures, construction technology, sustainability, and hisory+theory, with about 2hr lectures each, but your main focus is always design studio. The lectures become less important as you go on.
I never said there was NO social life, just a lot less than your typical 1st year arts/nursing/commerce student, the architecture faculty is also at a physical remove from the main campus, so it is hard to get involved in the main campus socs.
Infact 1st +2nd year, despite the work, were actually fun, there is usually a field trip somewhere which are always eventfull.
But if it is what you want to do, then yes, architecture, despite what could be called the pragmatic goal of making a building, is an exceptionally broad area, covering art, science, philosophy, history, nature, politics(?)... all in the name of making the places that we dwell in, and as such is an incredibly rewarding experience,
