Well, as Im sure you can appreciate, the commute is a wee bit awkward.
Im fairly certain we only get medics on the sqn, thats because they tend to go to uni with their cadetship/bursary already sorted. Therefore they have to be affiliated somewhere. I've only ever met one of them.
Basically, unless you can get yourself a bursary, you're better off being in the OTC.
Unless you're willing to rethink where you go to uni.
