More or less the same.
General rule of thumb, if you were popular with the girls in 6th form/college, you will be popular with the girls at uni. If girls weren't really interested in 6th form/college, then most girls won't be interested in uni. You will meet the same type of girls at uni that you did in college. The only difference I would say is, because there are more of them, taking the long term view over 3 years at uni, you have got better chance of finding somebody somewhere that takes an interest.
So guys who have never had any experience with girls before uni, may find a girl at some point during their three years, but they shouldn't go to uni with expectations that it is a sex fest and all these girls from different parts of the country are waiting to get with them in freshers week. There are more girls, but there is also more competition, there will be a lot of lads coming to uni who are experienced with girls, used to getting attention from girls and have the confidence that comes with that.
Bear in mind that a fair proportion of people, male and female, arrive at university lacking experience with the opposite sex. They all have the same uncertainties - how do you meet the opposite sex, how do you interact with them if you are shy, how do you deal with rejection, what if it gets to a stage of sex and you haven't done it before, will you know what to do? But it is much easier for the inexperienced girls than the inexperienced guys. There will be experienced guys who arrive at uni knowing that girls usually give them attention, knowing that they are sexually experienced and will know what to do in bed, and they have that fearless confidence that radiates off them. Girls can sense this, so the inexperienced girls who are wanting to have some new experiences at uni, will gravitate towards these guys (who generally will sleep around with a lot of girls) and will find the guy takes care of introducing them to sexual experience. But the reverse doesn't work because the experienced girls, are not looking out for the inexperienced guys, by and large they have their sights set higher on the confident experienced guys. So it is much harder for guys to start getting experience with girls.
