# Can I enroll in a closed registration course or after the course has started?

It is not possible to register for a course once registrations have closed.

Each course has specific start and end dates.

Registrations are typically open for 8 to 10 weeks before the course begins. After this deadline, registration is no longer available.

You can find the list of professional training courses with registration dates in [the FUN catalogue](https://www.fun-mooc.fr/fr/cours/?limit=21&offset=0&query=&types=12517) and all the latest training news on our social networks [**X**](https://x.com/unicamp_fr) *(Twitter)*, [**Facebook**](https://www.facebook.com/Unicamp.fr), [**LinkedIn**](https://www.facebook.com/france-universite-numerique) and [**Instagram**](https://www.instagram.com/unicamp_fr/).
