I applied for environmental science.

W GPA- 4.51
UC GPA- 4.11
UW GPA- 3.83
SAT- 1450
I have taken many honors/AP/college courses since freshman year.
I created the environmental awareness club during my senior year after deciding I wanted to study environmental sciences (did an essay about this). I have been a member of Liberty in North Korea since freshman year and am president this year. I have also done CSF and NHS. I have regular volunteer hours as well and have been working at a learning center since junior year.
I also applied to UCSB, UCSD, UCLA, and UCB, but I’m not sure how secure I feel about those schools. I just want to know if I have a good chance at getting in this school or any others!

Stats wise you look competitive but the application review considers everything including your EC’s and essays.
