<p>I think the weight of the GPA depends on the courses. If someone is taking all regular courses and gets A+ on all of them schools will wonder why he/she hasn't taken advanced courses, even if the marks would have been lower than A+--for example, a B+ in a ridiculously hard AP course. In this case, the GPA carries less worth than if the student has taken more advanced courses. </p>
<p>If I were the adcom, I would take the B+ AP'er over the A+ no-honors/AP student simply because AP is so much harder. </p>
<p>SAT is supplementary info about a student's reasoning/academic ability. While it is true that some people score lower because of personal problems or just human nature, the reality is that in competitive admissions assuming there were no extenuating circumstances, unfortunately it is, in most cases, the 2100 4.0, not the 1800 4.0 or the 2100 3.0, who will get the most favorable treatment. Of course this is by no means always the case--in wholistic admissions, and it seems to be existing in some schools--there are exceptions. </p>
<p>What schools need to realize (and fortunately, some are) is that GPA and SAT, while they carry a lot of weight, are just numbers and do not tell anything about the applicant as a person. People with ability and notable character, not necessarily those with high scores, should be more recognized.</p>
