All of the information you're looking for depends on what you're actually hoping to get out of your degree. The "computer field" has very different sides to it. It boils to down to 4 career types in the grand scheme of things.
1. You make hardware. I'm not talking about making PCB and copper out of thin air. I'm talking about designing the hardware.
2. You make the software. Computers, and electronics in general, are absolutely useless without the software to control the hardware, right? This could be the BIOS for motherboards, or working on software for Google or Microsoft.
3. You're the IT guy. Whether it's Geek Squad or a Network Admin for a large company, the world needs people who understand computers and understands people. If you've ever helped a friend or family member with a computer problem, you know exactly what I'm referring to. People can be brilliant accountants, doctors, business men... you name the career and there's a good chance they're retarded when it comes to computers. They, and the billions of people across the globe, will always need assistance with technical issues.
4. You're the guy that manages others in one of these groups. Sure, it might be less hands on and more meetings, conference calls, reporting to the boys "upstairs", and double-checking your underling's work, but hardware engineers, devs, techs, and admins all have bosses too.
So, with all that in mind, what are you wanting to do with your degree?
Also something worth noting, this is largely a North American forum. We do have some members overseas, but the vast majority of us are located in the US. Therefore, our view of the IT market is largely that of the US IT market. I'm not too sure how much it differs to Scotland or to any other country, but we'll offer the best advice we can.
