Affiliate Marketing Secrets

I have come to the stage of applying to sixth firm collages and I am unsure how to promote myself without sounding arragent. I also don’t now what things to stress, what they like to hear, how to let my passion and need to go to there school really eliminate through my application. How to make myself different from all the other applications they must receive. My niche is art, how do I show this. Help!!

I want to go into the field of graphic design or multimedia. What I really want to do is design templates, forms, planner pages, calendars, organizers, statements, etc.
What should my educational focus be on for that?
What kind of designer does that particular niche? Is their a name for that?
