Can I study Law at Cambridge and then go to Harvard law school?
You would need to look at the entry requirements for Harvard and how it is funded. I would also ask yourself why the top universities attract so many law students over here. Anything is possible in life but there are three degree subjects that fill every parent with dread as the costs are overwhelming as they so much longer and are so intense you cannot work in the holidays to supplement the costs. They are Medicine, Law and Veterinary School. Can your parents see you through to the end is what you really need to be asking, as these two will be incredibly hard to fund.
