A 'Forced' Gap Year

I was hoping someone could help me (or give me some advice).

So, this year I applied for several courses, in which I was rejected for 3 of them because my current course that I was doing, does not relate to the course that I applied for. Now, that was fine as in the end, I felt like this course wasn't right for me.
However, my other 2 choices were ACCEPTED (of which were the same course, I got declined for at other universities). I decided to accept one and decline the other in the hopes of obtaining a place via Adjustment and that I may change my mind at a later date.

Now that Adjustment is upon us now, I contacted a university in regards to a place in one of their courses, to be told that they are expected and due to go over the quota for places. This means that I am now stuck with a course and a university that I do not wish to go to.
I contacted this university this morning and told them that I would like to take a Gap Year and I am now awaiting a reply.

If my release gets accepted, does anyone have any advice as to what to do during the year that I am forced to sit out on? I recently received an A in HND: Computing Software Development and intend to apply for Software Engineering at University of Strathclyde.
