CSE Undergraduate Certification info?

Hello everyone.

Could you please tell me what exactly is the certification in CSE? I’m an Engineering Mechanics incoming freshman, looking to specialize in Computational mechanics, and this seems like an amazing add-on to my learning experience and resume.

If anyone has done it, could you please tell me how useful was it, how it helped your job opportunities and how is it different from a minor? I plan to do it regardless of it’s value or whatever, I am just curious haha

Thank you for taking the time and answering!
