CCC is the minimum requirement for all courses at the 13 Dutch research universities. A, A, D will not get in. It is an egalitarian system, so as long as you achieve the minimum requirement you will get a place. However there are exams every 6 weeks and if you do not pass the all the exams during the year, you are off the course. Hence, the high drop out rate in the first year.
DD wants to study in the Netherlands - Political Science in The Hague (taught in English). Her course is now selective (with a cap on the number of places offered), so she has to do an online test, submit a motivational letter and her predicted grades then be placed in rank order to be offered a conditional place of CCC. Other selective courses are medicine, Law and Aerospace engineering (at Delft).
Dutch universities have two long semesters (20 weeks each), so longer contact time than British secondary schools. There are 2 weeks off at Christmas, but no Easter holiday (just 8 bank holidays dotted throughout April, May and June - Kings Day, Liberation Day etc).
Teaching contact time is 20 hours per week of lectures, seminars and tutorials for DD chosen course and 20 independent study. Tuition fees are 2000 euros a year, but the Dutch government has just cut first year fees by half. So DD's degree will be 5000 euros. Her chosen university is 67th in the Times Rankings so higher ranked than Bristol, Durham and Warwick.
The university accommodation are big blocks of studio apartments. So cooking facilities in your room and an en-suite. However, rooms are completely empty- you do not even get a bed. Freshers week starts on the 19th August, which is the Monday after A level results. Freshers apparently spend much of that week helping each other assemble their deliveries from Ikea... bonding over allen keys!
There are interest free loans for tuition fees but no maintenance loans. That is the only downside; but it means DD will graduate debt free, so on the other hand it is a bonus.
90% of Dutch graduates go on to do a Masters, in the UK it is about 25%. So DD may end up studying for 4 years.
