Can I mention the completion of online courses as professional qualifications when applying to university? I am applying now to a postgraduate program in Computer Science. In the application, there is a subsection where I can mention my professional qualifications; I am wondering if it is appropriate to mention the completion of a web-development online course (on Udemy) with uploading the certificate of that?
If the courses are relevant to your proposed research area, then yes. I did (after consulting with SE experts), was accepted.
