21 years ago we decided that Harvard and MIT would make the perfect new location to complement our Pre IB Summer School in Oxford. The course is academically rigorous, providing students with skills and knowledge required to start the IBDP. It provides ample academic input on IB subjects whilst giving students enough freedom to enjoy their time together. It is also a great choice for students who are thinking of going to university in the US.
