<p>I don’t know if there’s any way to quantify how much an IB Diploma helps, but it’s definitely recognized as a challenging high school curriculum. The admissions officers know what the IB Diploma means and I would venture a guess that it makes you a pretty strong applicant on the academic side. However, I don’t know if would increase chances of admission any more than non-diploma student with an IB/AP/A-level course heavy curriculum.</p>
