Student Developer Pack timed offers?


I am currrently a student and I 'd love to apply for the Student Developer Pack. There are lots of timed offers.(“Free for 2 years” etc.) So I wonder when will the timing start? The moment I successfully apply for the Github Student Developer Pack, or the moment I sign in those websites who host the timed services using my Github account?

Thanks in advance! Really love this pack!

The moment that you apply Github Student Developer Pack to your account.
