I studied Music Technology as an a-level, AS & A2. 
Here are the two recording projects that I was required to do (one per year). These are prety much my first two pieces I've ever recorded/played in a studio & mixed. Guitar, bass, vocals (played/sung by me) & Cajon (courtesy of my Music Tech Teacher Mr Ben Love, played by him). 
 
First year I chose the song 'Never Too Late' by Three Days Grace - as an acoustic version, because my school didn't have a drumkit, but a fully euipped studio... werd, eh? Guitar, bass, vocals (played/sung by me) & Cajon (courtesy of my Music Tech Teacher Mr Ben Love, played by him).

Second Year, I learned from mistakes, and I think, I made an overall good mix with the song 'Songbird' by Oasis. Guitar/bass/percussion (played by myself) & vocals (sung by 'Frank', a friend of my teacher).

Anyway, how much of a disaster were they? 
Obviously here to learn. I can give some good idea as to why the first year was so crappy. A very steep learning curve! I had a little over 3 hours to record everything. Which is why vocals are out of time - not to mention we did have trouble with our patch-bay short circuiting and totally missing out the desk and going straight the the computer. 
 
2nd year sounds a lot better, but I kinda think it sounds a little 'dead' as a whole song. I don't know what it is. However, percussion too loud. but hey maybe my speakers at home, it sounded fine at 'school'. 
 
However, I still do realise that these are still very crappy mixes! xD
