I'm wondering if I should consistently be taking all 4 sections of PT's (not only for building test stamina) but because I've heard that one LR is usually harder than the other? Is this true? I've looked at the LR scores of full PT's that I've taken, and on 50% them I scored significantly better on one section than the other, but in the other 50% I scored roughly the same on either section. Does this mean some of the higher scores that I've gotten on Flex PT's have been skewed because I happened to only take the easier LR section?
