i've been solving the OG DS in parts and reached ques 120 with an accuracy of 85-90%. i thought this was a decent accuracy till i reached the questions after 120. i seem to have gone blank in DS and can barely solve the problems. i tried solving around 10 questions after 120, but i was lost while trying to solve them. i am not too bad in quant and score between 47-50 in the mock CATS. but this DS seems way out of my league. in fact, i guess i found the DS on the
MGMAT CATs to be easier than the questions after 120.
i've just solved questions from 120-130, so i don't know the difficulty of questions after that. the 120-130 lot was so horrible that i'm scared to proceed further.

anyone else who had the same problems in DS?
