Minikew, I hope your daughter is able to focus on her exams, and decide on options based on both on results and what she has learnt about herself through this year's process.
I posted this www.theguardian.com/education/2016/apr/30/cv-of-failures-princeton-professor-publishes-resume-of-his-career-lows on the Oxbridge thread earlier in the year, but it is relevant here as well. There is a huge element of chance, when competing for oversubscribed places.
I have been through this twice as in mid-March DS, applying for economics, was sitting on one rejection and waiting for three others, having decided he no longer wanted to go to his fifth choice. He was then rejected by Warwick and UCL. Four years on and he has just been accepted for perhaps Europe's best PhD programme. (In fairness, he has just failed the first round of the BoE assessment. His CV of failure continues to grow.) Our DC are entering a super-competitive world. Just one place and others will assume they have sailed smoothly through school and onto medical school. Not true. We know that each success has been earned not just by hard work but by resilience and determination. And as a parent it does not become easier at the point when you have no input into the process.
Good A level grades will keep doors open. These have to be the priority. A gap year is a great way to take breath and regroup. Best wishes to everyone's DC.
