You can change your SAT test date, but there are limitations. You can generally reschedule your test date up to a certain point before the test, usually several weeks but the exact timeframe varies depending on College Board's policies and any current circumstances. There's typically a fee associated with rescheduling.
To change your SAT test date, you'll need to log in to your College Board account and follow the instructions provided. Check the College Board website for the most up-to-date information on rescheduling policies, fees, and deadlines.
