Hi everyone,

I've just completed the MP and MSS lessons and was wondering...what do you all do when you 96% understand a lesson? I did some custom problem sets from the question bank, and was getting all right except 1 or 2 of the ones designated "hard" or "hardest" every section...do I move on to the next lesson? Do I stay here on MP and MSS? What else can I do to make sure I 100% understand this before moving on?

Thanks!
