During the first month at RMC, first years undergo FYOP - First Year Orientation Period. You will not be allowed to leave campus at all. You will be working from reveille (usually 0500 or 0600) until lights out (2300) with about an hour of personal time per day. You have basically no 'freedoms' (read privileges) other than doing what you're told.
After FYOP, once you complete the Obstacle Course and receive your cap badge, you will be welcomed into the Cadet Wing and afforded a higher level of privileges. You can go into town during the day when you have spares, provided you wear the appropriate uniform. You are allowed a certain number of After Duty Passes (basically evenings you may leave the peninsula and go into town) each month; I think it's 12 or something like that.
When you go into town during first year, you are required to wear the designated uniform (4's - a formal uniform) at all times. There are limitations on what kind of furniture you may have in your room (very little in first year) although in subsequent years, refrigerators, TVs, etc. are permitted.
Rumor is that next year, first years won't be allowed to bring cars to RMC (parking shortage).
You'll have more demands on your time than your Civi U counterparts (unless they work as well) because in addition to studying, you are a CF member and will be tasked with parades, events, functions, etc.
RMC is like a full-time job which requires you to stay in shape, learn a second language, successfully earn an undergraduate degree, complete military training, and perform tasks as assigned. It is what you make of it, and you get out as much as you put in.
Cheers.
