You might find it helpful to find out whether your students meet the basic knowledge and skill levels required to learn your materials. Use a pre-test to find out. Pre-tests are often paired with remedial materials.

Some instructors offer self-assessment pre-tests prior to the beginning day of class and offer students ways to catch up before the first day. Others provide time during the first week for students to do such things. Alternatively, you could pre-test prior to each module, week or topic.
