After failing the end-of-course exam, how long must you wait to retest without retaking the entire course?

• A. 7 days
• B. 30 days to less than 1 year
• C. 90 days
• D. 6 months

Answer: (B)

The key idea is the retest timing. If you don’t pass the end-of-course exam, you’re not allowed to jump back in immediately—you must wait a minimum amount of time to study and refresh your knowledge. The policy sets a waiting period of at least 30 days before you can retake the exam, and you have to complete the retest within a year of the original exam. So the valid window for retaking the exam is from 30 days up to but not including 1 year. That’s why the correct option describes a range of 30 days to less than 1 year. The other time frames are either too short or don’t acknowledge the one-year limit.
