PrepFactory offers students a great selection of free SAT and ACT preparation activities. PrepFactory focuses on helping students develop good test-taking strategies while also not boring them with dozens of continuous rote exercises.
This past spring PrepFactory introduced helpful features for teachers. When you register as a teacher and create your classroom you can also create specific assignments for your students on an individual or class-wide basis. Then once your students have started on their assignments you can track their progress, see where they need to improve, and suggest more appropriate review activities.
