Pacifico, can you go into more detail about what you said? I'm also getting bogged down in the lessons because of the problem sets just for LR. I try to really master the questions as much as I can, watching videos for ones that I thought were important even if I got them right, before moving on because I don't want to struggle as much and waste PTs when I get to that stage. Should I go through the course and then do the individual problem sets or only do them after regularly PTing?
