By the beginning of level 2, you should be familiar with all of the grammar concepts from level 1. Feel free to refer back to them as you continue into level 2 and 3. Level 1 consisted mostly of how different specific verbs worked and idioms. Now that you understand those concepts, it is time to start learning how to apply those concepts to different tenses! Remember, when you learn a new concept, the best practice is to find someone to practice with. Good luck!
