Help me about FreeCodeCamp certificate

Hello Guys, How many lessons do we have to get a FreeCodeCamp certificate?
Because I have completed 113 of 1408 coding challenges.

The requirements for each of the certificates is a group of projects. You can see the project sections on the curriculum page or you can see them listed with the associated certificates on the settings page.

No. There are several projects per certificate and you must claim the certificates on the settings page.
