Dear moms, I am in a dilemma, my son has been with the american curriculum for 5 years out of the UK and we are moving to london, he has an offer from both ASL and dulwich prep, which would you chose, is the English system a big advantage due to its structure. We are not sure how long we will be in london, that indefinite . Pls help if you have ever thought of shifting curriculums need help to decide . TIa
