No, you do not need to complete all the courses. There are mandatory courses, that are labeled as mandatory, and must be taken prior to being approved for listing services.

U&Pet requires Caregivers to successfully complete the mandatory training courses to ensure that customers receive the very best care possible.

You can add as many of the additional courses as you like, as they are designed to enhance your qualifications as a Caregiver, noting that some may have a cost.
