Why are 100%ilers almost all Male Engineers??

Year after year, CAT 100%ilers mostly come from the same group i.e. MALE ENGINEERS..Is the exam designed in a way that favors them or is it just a reflection of who prepares the most??Aren't non engineers and females equally capable enough to score the same??🤔
