Y12, applying next year. I am researching options. Leiden is my first choice... but with 700 in a year group, it might not be for long!
I am taking A level maths so UvA is an option.
I went to Leiden's student for a day in April and loved it. I am going to Leiden (The Hague) and Amsterdam in August to visit again.
June/July seems ridiculously late to get accepted. What are you doing about accommodation?
