Answer: Call the teacher at the right time.
Explanation: When you call the teacher you say your name, grade and what your calling for. You just review a few things about your module, (Module2). Or sometimes he/she will ask for a specific example.
If you want to be fully prepared read each lesson for that module and take as many notes as possible if needed. The actually DBA Lesson is a review of what is going to be on the DBA.
Tell me if this helps! :)
Have a great day! :)
