On paper – an unofficial score report will be printed at the examination site. 

TIPS FOR PREPARING FOR YOUR LICENSE EXAMINATION

1.    Read study materials that cover all the topics in the content outline.

2.    Take notes on what you study. Putting information in writing helps you commit it to memory and it is also an excellent business practice. Discuss new terms or concepts as frequently as you can with colleagues. This will test your understanding and reinforce ideas.

3.    Your studies will be most effective if you study frequently, for periods of about 45 to 60 minutes. Concentration tends to wander when you study for longer periods of time.
