Yes, you have the option to repeat a Principles of Manufacturing course if you wish to improve your score or understanding of the course material.
However, it's important to note that only scores achieved as a paid, verified learner will earn a Verified certificate. If you did not pass a course or you would like to retake the course to aim for a better score, you will need to pay the course fee again for each attempt. The verification fees are not transferrable across courses, so each course enrollment requires a separate payment.
Repeating a course can provide you with an opportunity to reinforce your knowledge, review the material more thoroughly, and strive for a higher score. It can be beneficial if you feel the need to improve your understanding or demonstrate your proficiency in the course subject matter.
