Path to obtain certification

I am enrolled in the RPA Developer Foundation course, however I have some questions regarding the UiPath RPA Associate Certification Training course because I don’t know what the difference is and what I want is to have a certification that validates my knowledge. Therefore I would like to know some guide to achieve an advanced certification. I have a co-worker who has earned the RPA Developer Foundation and RPA Developer Advanced degrees, however these do not correspond to the UiRPA and UiARD certifications. Finally, what I want to know is that if with the course I am in I will be able to obtain the same knowledge as in the certification course, if on the contrary I should leave it and enroll in the UiRPA course.
Thank you for your help in guiding me better.
