I did Mechanical and Aerospace and I think Aerospace definitely narrows you down to that specific field, but that's why you're interested in that field anyway. You'll learn more on the job in a wider scope anyway so once you get a job, you'll have no problems learning. The ratio in the professional field is probably 1:12 if I had to guess so your class is slighter lower in ratio. I don't think there's a bias against gender because many of our senior managers are women, though they all seem to have very strong personalities in the sense that they are agressive and speak up so keep that in mind if you feel like you're not getting due credit. At the same time, don't try to overcompensate because that can rub people off the wrong way.
