What would help me get into Harvard?

Colleges ask for unweighted GPA on a 4.0 scale. Everyone applying to Harvard and the other top schools have the highest grades in the hardest cles and very high test scores, and Harvard took fewer than 5% of applicants this year. You need all that, and you need a lot more. Right now, you don't have much of a shot - you don't have anything to make you stand out. Find a way to get involved in your major now - the bigger, the better. And if you don't know what you want to major in, don't apply to top schools. There are very few people who would actually benefit by attending them, and if you don't know what you want to do, you're not one of them.
