Hello Sufiyan,

There is a common belief that science students get an upper hand when the Quantitative part is considered because it is believed that science students are good with maths. 

But I personally believe there is no such thing that it is easier for the science students to crack CAT exam than the students belonging to any other stream. It's only about the hardwork and efforts you put in, this is the deciding factor. You need to be focused and consistent with your preparation and nothing can stop you from cracking CAT.
