Need some suggestions/ answer

Let’s say I have created a portfolio website for myself. Now the question is Can I add freeCodeCamp’s lessons as my project? I assume I can add the projects I have completed to get the certificate, right! Need a clear understanding of what I can add to my portfolio website from here aka FreeCodeCamp.

My webpage / website hosted on Github

You are free to give suggestion / advice on my code.

Yes you can add them.

Can I add freeCodeCamp’s lessons too?

You can post anything you authored.

You can, but I would argue that they don’t add value.
