Submission of certifications of out-of-uni courses

[cynthiiiiiaaaaa]

Hi all,

While I'm preparing for the MS in Financial Engineering, my background was purely focused on finance in my university and I didn't manage to take mathematics-related courses.
To fill the requirements, I took several online courses, some of which provide certifications, but some of which by policy don't confer any statement of achievement.

I'm very confused about whether
1) I have to hand in the certificates of my results for the out-of-university courses, and
2) I can still put the courses which don't give me the certifications, on my CV.

Is there anyone who can advise on this issue?

Thanks in advance!
Cynthia
