I already took SAT exam. during my registration I was not attentive enough and accidentally added an extra letter into my Surname. I noticed this mistake only yesterday(however i was admitted to the exam) and I am full of hope that there is still something to undertake and fix this issue. Could you please tell me if I can still have a chance to change information in the system after taking the exam and receive my scores?
Why don’t you just call College Board ASAP and work with them fix the error? That way when you send to colleges the correct name will be attached to your scores and they won’t go to someone else.
