Mona Lot - I am a university graduate and have just flown a 5-day stint with easyJet. Three out of those 5 days were with CTC trainees and 2 were with young, line-trained FOs (< 30 years' old). All 5 of the pilots I flew with in that time were University graduates. Not every pilot I fly with is a university graduate but the majority are.
For what it is worth, my original degree was in Electronics and Electrical Engineering. I personally found the sheer volume of information required to pass the 2 groups of ATPL exams more demanding than my engineering degree. Not everyone's experience I am sure, but that was certainly the case with me.
I also concur with all of Right Touch's sentiments.
