I would suggest you find a forum for students on the autism spectrum. I would,hope there is something out there that would give you some good guidance in terms of colleges, and college applications for students on the autism spectrum.
If you attended a public high school, your school would have been required to help you with a transition plan for post high school. Did they? And what did that yield?
Yes, you have a disability…but you will get much further discussing how you are compensating for your areas of weakness, than using them as a reason why you should,be accepted to very highly competitive schools (which…BTW, are competitive for typically developing students as well).
