No they are not. Men and women differ in social conditioning and parameters. Due to this, we have predisposed men to a lot of rational jobs and women to a lot of emotional work. But as far as brain is hardwired, no difference as such exists.

Touch wood, many of my female maths students are/were brilliant mathematicians. Almost all of them are/were school toppers and almost every one scored above 95 in maths in their boards. Quite a few got top scores in IIT JEE.

It is only in the mind and conditioning of society and nothing else.
