However, if you have not been studying the worksheets for a while, you will be asked to take a Diagnostic Test. Based on the test results and an interview, the instructor will determine your starting point. If the test results show that you have forgotten a significant amount of the material you studied previously, you might have to redo some of the worksheets.
