Private Internet Access ($3.33 monthly/$39.95 yearly) and boxpn ($3.75 monthly/$44 yearly) are both pretty cheap. Even for the poorest student. Just skip the pub this weekend and that should pay for your year with either provider.
Also, if you pay for your internet access you could consider a switch to Acanac as they provide VPN access for free with their DSL or Cable service. Personally though I'd pay for VPN as that allows you to quickly switch services if you aren't happy, its much harder (or at least less convenient) to switch ISP's.
