HS Junior.. what are my chances?

<p>Okay, here we go.</p>

<p>I am a junior in high school trying to boost my chances of getting into a good college. I took the Pre ACT and am very disappointed in my score even though I am usually a straigh A student. I was wondering if colleges offer scholarships for academic grades other than for scores on the ACT and SAT? I also am a hospital volunteer, involved in a program called women in medicine,philanthropy club, ambassador club, club volleyball and am attempting to get into key club and traveling science show. I want to do Science Olympiad but I don't know if I can do all the work with my schedule. Should I join Science Olympiad? I took AP psych last year and this year am taking AP Bio and APUSH, forencis, algebra 2, honors english, spanish 3. next year i will take precal and anatomy & physiology, spanish 4, AP english, government, MAYBE AP chem or AP physics. Is this enough? I want to become a doctor but I don't know if I will be smart enough.</p>
