Help into getting into a good college w/ low income

Thank you a lot for your help. I am planning in majoring into something involving math and science, most likely something involving engineering. The reason I think I should take Art History is because it fills out my art requirement for high school. Keyboarding is something that I am also interested in, as I have a quite fast wpm (120) and the class teaches you how to format letters, documents, and such, which I find fun. Like you listed, my EC’s do sound all over the place. I am going to follow your advice of taking EC’s in areas related to my interests. I am thinking Math Club, Chess Club, and Academic Club, along with track. I am also doing volunteering, and with the amount of hours I am gaining per year around 30, I think I am on the path into getting into National Honors Society, along with German Honors Society.

Can you recommend me more ways to make my application more appealing for Colleges? I really want to get into Rutgers on a full ride, or Stevens on a scholarship because it will save my parents a lot of money.

On the path that I am going, is it possible for me to even get accepted into Stevens? I know that I still have a long way to go, but is it even possible?

Thank you so much for your help.
