DD has high hopes to apply to do Economics at Cambridge University next year. She has spotted a two-week online Summer School for students who hope to study economics at Uni, which is being run by a local independent school. The cost is £700.
If she attends this online summer school, is it likely to improve her chances of getting into Cambridge University? It's a lot of money to waste (and also time) if it wouldn't make much difference.
Any views would be very welcome!
