Levels beyond "Advanced 2"?

In the table of how many words you need to complete each level in LingQ, it only goes up to Advanced 2, I´m seeing “Advanced 3” in other places however, for example:

On my downloadable certificate, it say I´ve achieved the level of Advanced 3 in French.

This is what it says on my avatar page:
Your Avatar Level: Advanced 3
To next level
7562 Known Words

So do I get a certificate for achieving “Advanced 4” when I´ve added these 7562 words? And are there then further Advanced levels after that?
