If you're doing Udemy or any course over the lockdown don't just share the certificate.

Share few more things to assert that you didn't just hit the "play" button. That you learnt something. Ideas below.

Create something out of the course, host it, or just take screenshots and post along with certificate.

Write a blog on what 5 or 9 things you learnt about the topics.

Write a Twitter thread explaining 10 words from the new vocabulary.

Do a Twitter thread reviewing the course: instructor, pace, content, exercises etc.

A certificate today has zero value. Show your learning through your content.
