I'm registered for the June test date and I am nearly through with the more recent test questions not reserved for full PTs so I've resorted to doing drills / sections of older questions. I mainly study by doing full sections rather than a bunch of shorter drills so my main issue is that I'm running out of sections that fully consist of new questions. I've definitely noticed differences in question structure between the new and old LR sections, but its hard for me to tell whether there is a significant change in difficulty between the two. I have been doing better on the old ones vs the new ones so it could be that I'm finally starting to master the LR section (hopefully) or it could be due to easier questions.

Does anyone know if the old sections are actually any easier than the new ones? If so, what would be a good study practice for someone who doesn't have very many 'fresh' questions left from more recent PTs?
