Hello Luana, thanks for the questions.

1. We don’t have a pre-determined time limit on when you need to take the exam after purchase. However, we recommend that you plan to complete it shortly after purchase to ensure you have access to the most recent version. We strongly encourage completion within 90 days.
2. If you have purchased the exam WITH the course materials (either as an instructor-led event or self-paced eLearning), we have an open-book policy. This means that you can refer to all course materials during your exam time. 
3. You are not required to complete the course before taking the exam. The exam is directly aligned to the course content so we recommend completing the course first, but it is certainly optional. You also have the option to purchase JUST the exam without the course materials if desired.
