Letter of appeal?

<p>Hey guys,
So I know admission decisions haven't come out yet, but I'm positive I got rejected from UCSB, which is my dream school. So far, I have been waitlisted at UCSC and UCD. I am definitely going to appeal to UCSB so I wanted to start on my letter early. I was really hoping I could get some help as to how long my letter should be, what I should include, basically anything that can strengthen my chances of getting in! I am planning on writing about how I applied under computer science but want to be reevaluated under Chemistry.
Here are my stats:
UC GPA: 3.7
ACT: 26
Major Applied: Computer Science
Major Appealing For: Chemistry
AP CHEM: 4
SAT II CHEM: 720</p>

<p>Any input would be much appreciated!
Thanks!</p>
