So long as you provide supporting documents from a doctor, you'll be fine. You should also send documents from your school proving that you received additional time - assuming that you did. If you didn't, I don't think it'll be that big of a problem…
@Burden.of.Floof @DontPay4LawSchool @fjb627 Thank you all. I guess I won't put too much weight on my diagnostic! Will start it tomorrow, excited to see my score however.
