How do I sign up for the SAT and ACT?

You can register for the SAT at collegeboard.org. If you took the PSAT, you probably have a CollegeBoard account that you can use to register. You can sign up for the ACT at act.org. In both cases, the registration process can be a bit lengthy. Many of the questions are just for internal research purposes, so don’t sweat the details too much! Be sure to carefully pick the correct test date, location, and accommodations (if applicable).
