Am i able to get into a college/university?

[sammmy]

I am a sophomore in high-school, im really worried about college. I was new to a school last year as a freshman, i didnt really have alot of friends and i had alot of problems at home. My GPA last year was horrible. i currently have a 2.6 gpa as of sophomore year, added with last years i have a 2.4 gpa. Im trying to study really hard and i am doing a volunteer program close to where i live its an EMT corse and a bunch of other volunteer programs im doing as well, such as helping kids with special needs and working in hospitals around my area. This summer i am also going to a camp that will give me 100 + service hours and a congratulatory letter from the president. Im also in a club and i play a sport. i know these look good on college apps. I have calculated that i can get a 2.9 gpa by the end of junior year. I am really worried about getting into a college i REFUSE to go to a community college. I have been researching different colleges that accept 2.5-2.9 gpas on collegeboard.com there are a lot that do accept gpas in that range. I also need help with study skills, how do i prepare for a test? how do i get more organized? please help!!
