How to get into Brown University if you are dyslexia?

I don't see any reason why not especially if you provide a good solid personal statement stating why they would be lucky enough to have someone like you go to their school. In regards to your test taking..does your school have a program for student with disability? If so, they'll be able to provide you help in taking your test through proctoring-- it allows you to take your test with extra time. I know my school has it and its called DPSS (Disability Program Student Services) which I utilize myself. My GPA went from 2.5 to 3.8 just by being able to take my test with extra time. Good Luck but don't give up until you try.
