DP and I want to give DSS1, who is 16 and in his penultimate year of French lycée, a tiny introductory idea of what university life in London might be like. We are going to spend some time in London over half-term and want to show him Imperial College, UCL, LSE and King's College - at this stage, it is about showing him the physical locations so he can compare and contrast with French grandes écoles. We would also really love to show him some halls of residence, as leaving home is a big deal for DSS1. Can anyone give me any useful clues?
