How difficult is it to crack CEED and NID DAT for MDES

Ceed: You need to be very good at drawing part for ceed. Part A is quite easy but Part B is where everything get tricky. NID DAT: Personally i feel NID quite easy as most of the question are oriented toward discipline specific questions. So drawing those things comparatively easier. Due to that reason i able to went till final round of NID but couldnt able to get good score in Part b of CEED.
