As I am spending most of my time working on recent PTs for the December test, I have been solving some of old LR questions as well (I would consider PT 1-30 old).
After working on both, I think a conspicuous difference between old and newer ones is that old LR questions are not as tightly worded as new ones. I feel like old ones are cruder while newer ones are more refined in terms of their writing styles.
Assuming there are differences, I don't think they are about different flaws or different assumptions but more about different writing styles. I don't know if this is just me but I definitely spend more time reading/understanding old LR questions' stimuli than those of newer ones.
Do you guys think that there are any differences between old LR questions and newer ones? I would love to hear your opinions about this :D Thank you!
