I tend to fluctuate in the LR section. I want to improve it to the point where I get a -3 or -4 consistently. Now the problem is when I get a practice test that has two LR sections, I tend to do great in one of them and okay in the other. I have checked the difficulty levels and they both tend to be similar. Any advice on what I should do to achieve my goal? Should I be doing more drills to see where my problem is?

How does everyone use live commentary? I just want to see if it is helpful and in which ways do others find it helpful.
