60 days trial - can I extend the period?

Im a newbie with Linux and using the Lab for learning Linux RedHat.
Now I have a 60 days trial RedHat Enterprise 60 days trial and only a few days left.
Is there any possibilities to extend the trial period because I´m not finished yet.
I really appreciate your answer if it's possible and and how to do it

Glad for all the answers I can get from this forum
