In Leeds, my first 2-years were the EEE course, while in the 3rd year I picked a few modules such as Optoelectronics, fibre communications and a few other embedded modules with FPGAs and MCUs to obtain the title "Electronic and Computer Engineering" - long story short, we had less then 5 girls on the course, and my memory is quite fuzzy here cause some looked like guys ...or ...well, just very hairy girls (I think one had a moustache). The ratio here was quite easily (girl:boy) 1: 25
*shudder*
The Masters was a bit better as there were some actual 'easily identifiable' girls and the ratio here was ~ 1:10 and a much smaller group of students as well. There was one girl I met though, she had beauty and the brains to boot and was definitely operating at a different "level" than most of us...now that was well rare.
