I think the IB curriculum is scaring the general public of the level of difficulty. It is a diversified curriculum aimed at giving the students a broad range of knowledge in different subjects. IB, which is offered in less than 1,000 schools, may not be any more difficult than any other 14,000 private and public high school curriculum which doesn't subscribe to the IB system. The U.S. colleges don't necessarily compare IB scores with A level grades as they do in England. The grades which the students received in their high schools, i.e. A or B or C are the determining factor in admissions and not some aggregate scores. I would not prejudiced against any schools which offer IB and not apply as long as the school offers first class education and has a good reputation.
