<p>So I meant to sign up to take the SAT tomorrow but instead signed up for January. My mom wants me to go tomorrow and see if they'll let me pay the standby fee and switch dates. On Collegeboard it says you can change test date for a $21 (something like that) fee but tomorrow isn't a date I can change my test to. Do you think if I went to the standby room tomorrow they'd let me pay $21 on top of the January fee I've already paid? I do not want to go tomorrow and pay the standby fee for tomorrow which is $42 + normal fee and I wouldn't get a refund for the January test. Anyone had any experience with standby and changing dates?</p>
