My #1 daughter is finishing up her CS degree at a top 10 CS school. Her comment was that they intentionally decimated the field with three killer gateway classes during which 2X as many women dropped the major compared to guys. In a couple of the 400 level classes she has been the only woman taking it. The good news is that she thinks nothing of it.
The bad news is she wants to go into testing vice development. Thats good for the world in generally (we need more software testers), but bad for me since it dramatically lowers her chances of becoming the next Bill Gates and I will actually have to work long enough to retire.
Testing can be more fun than pounding out code, or it can rival working on the dreariest assembly line.
Good luck to her finding the inbetween.
