Help please! College of Engineering & SAT scores (UCB, Cornell, Stanford, etc)

Thanks everyone for the advice!!!
Another thing that I’m concerned about is the CoE supplemental essay. I’m not sure how to display my interest in engineering specifically. The big problem I have is that I don’t have any ENGINEERING experience. This being the case, I have absolutely no idea how I am going to convey my interest in engineering without any engineering experience for the supplemental essay. (I’m interested in engineering because I like solving problems (broad, I know)). As I’ve mentioned above, I want to major in bioengineering or biology and have demonstrated interest in biology/research. I’ve only looked at the Cornell CoE essay, and I couldn’t find one for UCB and Stanford (is it correct to assume that they do not have one for frosh applicants?).

For more info, I’ll just provide my stats below (perhaps there’s something in here that I could use in my CoE essay?).

Given the feedback that I’ve gotten, I have decided to apply to the College of Engineering.
My schools list as it stands includes UCB, UCLA, Stanford, Cornell, University of Washington (in state applicant, safety), RPI, and NYU. Of this list I’ve only found a CoE supplemental for Cornell (hopefully this is the case so I don’t have to worry about it so much!).

Male, Asian (Chinese)
GPA: 4.0/4.0 UW, 4.33 UC GPA (only male in my class w/ 4.0 GPA) Top 1% of class
SAT: 2280[2290 superscore] 780CR,730M[740M superscored], 770 W
SAT II expected scores: 780+ Math II, 780+ Bio E
9 AP’s: World Hist 4, AB Calc 5, English L&C 5, US Hist 5, Psych 5
(Sr year AP’s= BC Calc, English Lit, Physics, Stats)
All core subject classes are either honors or AP exclusively

EC (listed in order of importance to me):
**Authorship on a published scientific review (collaborated with researchers at Fred Hutch Cancer Research Center). Based on recent research done on cancer growth inhibitors.
Community College Biotech lab volunteering (2 weeks [17 hrs] so far, might do more)
Debate club officer (“Captain”)
Science club
Orchestra all 4 years in HS (7 total)
50+ hours volunteering sorting food at local food clinic
NHS
Random unofficial peer tutoring (does this count? a lot of friends come to me for math help, and I spend usually 1-2 hours every time tutoring them)

Awards:
1st in statewide science competition
1st in division orchestra festival/2nd overall
Commended national merit scholar
Student of the month
AP Scholar w/ distinction

**I’m not sure if this is as glamorous as it sounds. Basically I spent a few weeks researching very high level science, and was asked to design an image depicting the processes involved in cancer growth inhibitors which was included in the review paper (so I was listed as an author). It was several months in length, and a lot of time was invested learning about the dense topic of tyrosine kinase inhibitors.

I’m sorry for asking so many questions! I’m just super stressed right now thinking about all of this stuff!
