I looked up your institute online just so that maybe we can be of better assistance. :) There isn't that much information posted there, but I did find out that your program is only 1 year long. You spent approximately 11,050 USD. 10 months at my school costs me 35,000 USD. It's also a 4 year program. At my old school, I spent roughly 20,000 for 10 months and it was also a 4 year program.

Transferring schools is something that happens only when you can't do anything at your own school, or if you're planning on building up your GPA to get into a better one. McKay also offers Criminal Justice, Medical Administrative Assistant, Medical Office Assistant, Veterinary Office Assistant, Massage and Hydrotherapy, and Photographic Imaging Technician Programs. Where this is only a 12 major program for the Graphic Design, I really wouldn't worry about whether you're going to do superbly or not. There have been a lot of classes that I've taken, and I've also taken quite a few for my major and minor. Of course, you'll need to do average or above in your select classes... But where it's only a 1 year training program I don't think it's as intense a commitment as a major in school.

Here, you really just need to have confidence in yourself. Once you start, you'll have to remember that you're always going to think that you are the worst one in all of your classes. Believe it or not, other people will be thinking the same thing. Just chug through it and you'll be fine. The pressure you're feeling from your parents should still not affect you. As long as you're trying your very best, you have nothing at all to worry about.

You seriously wont.
If you were admitted, then the coursework won't be too difficult.
Also, the Institute's aim is to produce successful individuals. If they can't do that, then it's a problem with the Institute, and not with you.
