The pairing problem in the real test was impossible for me

While practicing in gregmat and with ETS guide questions the SE questions were easy as long as you were able to pair but in the real test I was able to pair all sets correctly but I just couldn’t make out the logic of the sentence.
The logic was insanely hard. What’s going on - I want to request Greg to do a class on SE questions with extremely difficult logics.
