I have been going through chem paper 2 from past papers but I rarely find any of the papers challenging. However I have not gone through all the past papers so I am wondering if I have missed a difficult paper. Do you guys know any paper which is tough enough?
Thanks in advance.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
