>>1 So was the course you wanted an art course and you didn't get into it?
And there's nothing wrong heading in the direction of science. That is, continuing with a science field. At least you have a fallback plan if an art career doesn't work out. Basically, you can pursue art after you do science. At least a science degree guarantees you (more or less) that you'll find a job to make a living. Then you can shift gears towards art and see if you get it to work out.
That's exactly what I'm doing actually (though in my case I realized late, like two years into my science degree, that I didn't enjoy science at all and was just going with the motions).
Also, competition with yourself is good, but competition with others is also important. It allows you to have a reality check and see where you're standing, if you need to work harder, sets a level you wish to reach, etc.
