Um yes...that should define who you are academically. Someone who takes a ton of IB classes and does well in them are obviously more committed to their academics than those who do not. Colleges see people who don't take a bunch or rigorous classes and underachievers and not academically strong.

yeah.. taking rigorous classes look good on you academically, i agree, but there are others who are successful without taking those rigorous classes so i don’t have to agree that not taking those classes make you an underachiever in a way
