You may know that almost 70% percent of ECAT 2016 was repeated from ECAT 2014 past paper.Chemistry especially was repeated about 90%.There were people who had solved that and the paper was nothing but just just a piece of cake.
This paper may or may not come in 2017 but this paper will give you a deep insight of how the paper will be and it's difficult level.
