Hi mate, welcome to the forums. If I was in your position, I would train maybe 2 or 3 times a week to start with (depending on your current level of fitness), then build up from there. Do not overdo it as you will either a.) Injure yourself or b.) burn yourself out.
I hate to sound like an old man here, but also don't train so hard that it effects your education. That is most important right now for you mate

PRMC can be put off a month or so if needs be.
A lot of people will have different opinions here mate, so listen to them all, not just mine and do what you feel is right for you
All the best and let us know how you are getting on.
Dave
