What are my chances at getting accepted into schools such as Cal Poly SLO, UCLA, UCSD, or UCI?

I’m currently a junior entering my second semester of the year. My current weighted GPA is a 4.1 and my unweighted is a 3.8. I’m in the IB diploma programme at my school and I also take dual enrollment courses at a local community college. Once those classes are added, my gpa should boost to a 4.3 weighted. My UC GPA is a 3.9. I have yet to take the SAT or ACT but will be taking it the following week. I have the following extracurricular activities:
*Although I am a junior, (4rs) means I shall be pursuing the activity senior year)

  • Band (Wind Ensemble) 4 yrs
  • Winter Percussion (2yrs)
  • Pep Band (2rs)
    -Marching Band…ranked 4th in California (4rs)
  • I have performed with the band at one of Disney’s Performing Arts centers in Orlando, Fl

  • Participation in Trio Upward Bound summer session. We created a cultural event and this is also where I took two dual enrollment courses (3rs)
  • I have volunteered 100 hours at my local retirement center
  • I have work experience in regards to doing concrete(4yrs)
  • I partake in meetings with my school’s IB Council, where I am the treasurer
    -EAOP, I’ve participated in events such as Ceaser Chavez Day at UC Davis and I have attended Discover Engineering at UC Davis

    Anything helps, thanks!
