My experiences support what @JilltheTooth has already mentioned.
When I was applying for college (undergraduate) it depended on the institution. Actually, I was told by representatives from a couple different institutions that SAT scores do not matter as much anymore. For some reason, I was under the impression this was a new thing and would only continue in the future (I applied in 2000). So, maybe SAT scores matter even less now?
It also may depend on your major. Some schools require a separate application to get into certain programs. I had to write a completely separate paper to get into the philosophy department (it only accepted 20 students a year).
Colleges are also starting to appreciate the value of service work more. My advice to you: volunteer. Find a cause you support and feel strongly about, contact a non-profit in that field and volunteer (even if you can only work 5 hours a week). Not only does it look good on college applications- it’s good for your soul! (coming from someone who is about to begin her non-profit career…)
