1. Schools will look at you and say, “He did so well on his SATs; he must not have been trying hard enough in his classes.” (I don’t have the article handy, but remember reading one not too long ago about admissions at UPENN, and they referenced a girl who had high SAT scores and a B average, and they rejected her outright because of it.)

2. There will be people with your SAT scores who ALSO have the high grades to go with them.

33/42 is what, a high C? Will it be weighted at all? Is that cumulative of every class you’ve taken? If you’ve excelled in some subjects but not in others, that will certainly be taken into consideration.

You certainly have the ability to get into a good college, but that depends on what you consider “good.” A C average in an IB course is not a route to the Ivy League, but there are other schools that would be happy to have you. As for scholarships, you would probably be best applying to “safety” schools–schools where the average students’ scores and grades are not as good as yours–where you’re more likely to earn merit aid (scholarships). Additionally, you don’t say what year you’re in. If your grades for other years have been better, your chances of getting into a good school are better as well. Colleges will also take into consideration extra-curriculars, recommendations, class rank, and your essay.

Good luck.
