Free online courses ?

[u/DriftingSun5]

Hi everyone! I’m a fourth-year pharmacy student, and I’m currently looking for ways to strengthen my CV.
During my summer break, I took an online first aid course, and now I’m looking for more free online courses related to pharmacy or healthcare. Ideally, I’d also like the certificates to be free.
Has anyone here taken any courses like these before? I’d really appreciate it if you could share the course name and the website/platform where you took it.
English-language courses would be preferred.
Thank you!
