What will colleges specifically look at on your high school transcript? I had a pretty rough start..

I had a rough freshman year. I got a 2.6 (These are all weighted BTW) GPA first semester. Second semester, I got a 3.4. Sophomore year first semester: 3.4 GPA as well. Second semester sophomore year: 3.6 GPA. I also got 1000 on my PSAT.( 500 in both sections) Both freshman and sophomore classes I took Honors English and Honors Biology and Chemistry, respectively. I also took a summer class to get ahead (Spanish 3, A in both semesters) Then I really started to understand how to get A’s when Junior year started. First semester of Junior year : 4.0 GPA. This year I took 3 AP’s (US History, Physics 1, and Psychology, and got B’s in them), scored 1280 on my PSAT and second semester : 4.2 GPA(Got A’s in US History and Psych). Also past three years so far I was in the Track team second semester. And I joined Cross Country my junior year for first semester. Junior year and sophomore year second semester I took 6 academic courses and 1 sport so 7 courses total. I took a real SAT from the collegeboard study guide book and got a 1340. I have registered to take a legitimate SAT on June 3rd. So as it can be seen, I think I really improved. What would a college admission officer think when he or she sees this? I also have 50 volunteer hours. I mean, from a 2.6 to a 4.2 really shows what I can do. Thoughts and criticisms are welcome. Oh, if you’re really wondering how I went from a 2.6 to a 4.2: I was honestly trying to get good grades but I rarely studied and had too many distractions (talking in class, clash of clans (really), etc… At the end of first semester, I realized that I left myself and others down and that keeping this up won’t get me anywhere in life. So I sat by myself in the back of the classroom of my two lowest classes the previous semester at the start of second semester. (with teacher’s permission). I uninstalled clash of clans. I really started studying for tests (usuallystarted four days prior to test) and I kept this up throughout sophomore and junior year. Except now I don’t sit by myself. I have just learned to not let anything get my full attention.

You will be fine. You didn’t state what schools you’re looking to apply to, but you will get into a college as long as you don’t solely apply to UCs or Ivy leagues.
