What is the cost of an online course?

What do I need to take a course?

No. The course is self-paced and will be broken down into short pre-recorded video segments with periodic assessments to check on your progress.

What do I receive for taking this course?

You will receive a final grade but the grade won't be on your proof of completion. To receive a proof of completion, you will need to achieve 65% on graded material. There are three different types of assessments within the course: quizzes, labs, and a final exam. Quizzes don't count toward your grade but will help you check your understanding. The labs will comprise one half of your grade and the final exam/project one half of your grade. Unfortunately, due to a large number of students and in the interest of fairness, late assignments cannot be accepted.

Will I be able to get help?

Each course has an active online forum where students can help each other. In addition, the MongoDB engineers will monitor the forums and try to help.

Do I need to pay to use MongoDB Enterprise for this course?

Not at all! MongoDB suite of products are free for evaluation purposes and no need to worry about licenses.
