TP4S occasionally offers a free practice SAT or ACT as a service to Lehigh Valley high schoolers. Space is limited, so register early. We ask that only 10th 11th and 12th graders register. We will contact you after you register to ask whether you’d like to take the SAT or ACT. On test day, make sure to bring a calculator, pencil, drink, and snack. The test will be from 9:00 until 12:30.
