I am a chemist, but your interests sound very similar to mine at your age. It is not too early to begin exploring the colleges/universities you would like to attend. I say this because they all have rather specific expectations and requirements for admission, and you need to be sure your high school course of study and extracurricular activity qualify you for admission to the schools you want to attend. I suggest you look at several types of colleges and universities, both public and private, large and small, and include some liberal arts colleges like Reed College, Amhearst, Oberlin, and Harvey Mudd.
Do not underestimate the importance and value of learning to write really well. Read as widely as you can. Most college educations will severely stress test your ability to read quickly and comprehend thoroughly, so highly developing your reading skills is critical. A serious mistake of many prospective scientists is to want to study only math and science to the exclusion of language arts, yet success in science depends heavily on your ability to communicate verbally and in writing extremely well. Knowledge of foreigh languages is often a requirement. Do not neglect interests you have in sports, art, and music, and develop your interpersonal and social networking skills as much as you can. Your goal should be to become as “well rounded” as possible.
Many high school activities have great value. Debate can hone your research, analytical thinking and persuasion skills. Participation in science fairs can give valuable experience and possibly lead to scholarships. Many colleges value and some high schools require volunteer community service. Experience in the performing arts and competitive sports can have great lifelong value.
You are embarking on a great adventure. I wish you great success!
