I actually knew about all those disadvantages, but some of the ones named aren't present for majority of the people at my school. And the way my school is set up, all my electives fit in during the school day, I'm just limited to two electives. And I will admit, I am having difficulty in finding Creativity. But in my state, if I graduate with the IB diploma, I automatically receive 24 hours of credit. For advanced students, yes IB doesn't help you.
