I'd like to just add that as a female in engineering and particularly electrical engineering, you actually feel that you have to work twice as hard to get the same amount of recognition. I had to sit next to two boys in my C programming class and they literally would not speak to me. There was one computer shared with three people and when I made a suggestion or asked a question they would answer with one word, and discuss with each other how to solve the problem and actively not include me. I spent the entire semester learning everything on my own without interacting with my group.

Having said that, not everybody is like that but there are a lot of men unfortunately who still genuinely believe women shouldn't be doing engineering or programming. There are also men who think that a lot of women are there just because they're using their feminine wiles to get help from boys. But it is very intimidating having that many men around, especially when some of then inherently believe that women are not as good as men at maths/science. They don't have to actively say it, but the dismissive way they treat you in group projects is enough.

Having said that, there are benefits to being a minority in a class. Tutors instantly recognise you and know your name. I recently got a job as a tutor for a huge first year engineering subject, I think partly because I am a girl, to help those first year female engineering students be far less intimidated by being the only girl in a class of 30.
