@IThinkIMadeItWorse STEP is brutal, year after year students hit the top grades but do not get their place at Cambridge because of STEP. Cambridge house their students in their colleges for all 3 years of the degree, therefore they have a very set number of places that they don't want their offered applicants to succeed. The natural grade boundary curve helps and STEP ensures a lot miss out.
For computer science Cambridge pays for TMUA which they call CTMUA for Cambridge Test of Mathematics for University Admission. For the other unis like Warwick, Durham, Manchester, they don't require it but some of the London ones possibly do. Start them looking now. Ds had a spreadsheet to keep track of everything he had looked at.
@gogohmm I think parents are more invested usually because they are expected to sell a kidney pay toward their child's uni costs. The minimum maintenance loan doesn't even come close to covering some first year halls of residence. Ds was grateful to have 2 parents to talk things through with. Dh and I had very different experiences of uni.
@middleager definitely start them looking now. See what courses are out there, maths can be combined with lots of different subjects, same with computer science. There are different entrance exams and the whole of year 12 summer to experience, read, watch, attend summer schools, complete courses and do things to pack out their personal statement plus practise papers if they are going to have to sit an entrance exam.
There are campus unis, city unis, some sprawling across the city, each one with a different feel. Best to feel it full of students which means either Feb or May half term. Look at accommodation offered and costs. Some like Warwick have a wide range of prices from £85 a week for a 40 week let or at their top end £218 a week for 40 weeks so a £5k difference for a room for their first year. That is self catered for both.
This is why I suggest research starts now. It is so much more than grades and courses. Plus it can motivate them for their year 12 mocks.
