dude, if you can't get spots at gigs i suggest have a gig of your own. it may seem impossible but it's really not. i use to be in a band and we've done several shows in our town. i live in the united states, i assume our scenes are completely different so i dunno if this plan would work but for the heck of it since you ask here are the things that we did:
1. get a place for your band to play at (one of my friends backyard was big enough we did most of our gigs there), of course your gonna need extra space for the audience which is the most impt. factor
2. where do you get the audience? parties, assemblies and events like that. i'm sure there are some activities like those going on around your campus. in your case you cant afford to be picky cause you really need as much publicity as you can.
3. if you or one of your closest friends are gonna throw a party, that's your chance! talk to some bands you know and get them to open up for your "little rockfest", you be the headliner of course!
4. record demos, spread the word about your band.
i can't think of more things to say...
5. ... oh and last, HAIL SATAN.
