I've got a Master's in Systems Engineering... There weren't any hot girls in my SE classes! Except one, but she was WAY too conservative about stuff so I didn't go for it.
I did CS for undergrad, and CS at my school was dominated by asians and indians, we had like 3 black kids (one of them was actually Ethopian... not sure if you'd even count that as black) and maybe a few hispanic kids. There was one attractive girl - skinny Russian blonde with small boobs (skinny Eastern European girls...

) but that's it. There were a couple indian girls but they were absolutely awful. And a couple of ugly asian girls. With asian girls I think it's either, they're cute, or you're ugly... no in between "average" looking ones

I feel bad for you CS guys, but here's some advice if you wanna meet girls... take some art and geology courses on the side. CS was desolate as far as ass went, but OMG at some of the chicks in my art and geology classes. And as I've found out pretty recently, art girls are HORNY.
