and welcome to the Rocket French Forum!
Rocket French Premium course includes different contents like Interactive Audio lessons, transcripts, quizzes, Grammar and Culture notes,...
I always recommend to spend most of your time on listening to the Interactive Audio Course.
Listen to a lesson once, and then listen to it again a day later to see how much you can remember. Once you feel comfortable move on to the next lesson.
Being able to speak French is so much fun and you will see that the language and culture lessons will seem much easier once you have an understanding of how to speak basic French.
After doing the first 3 lessons start reading through the Language and Culture lessons and do the exercises.
It pays to play one of the MegaGames (save MegaVerbs for when you are through most of the language lessons) 2-3 times a week. These games will teach you many new words and expressions in a fun way.
I hope this helps :)
