Chance me - ME/EE

I started to complete the application for Cal Poly SLO, and I wanted to know what my chances are for my selected major. SLO is my top choice if I get in.
Major: Mechanical or Electrical Engineering (in the process of deciding)
CSU GPA: 4.25
Coursework: AP Chem, APUSH, AP Physics, AP English Lang, Pre-Calculus H, AP World, 4 years of Spanish
Senior year: AP Comp Sci, AP Physics C, AP Calc BC, AP English Lit, AP Gov/Econ
SAT: 690 CR, 670 M, 600 W
ACT: 30 E, 33 M, 30 S, 32 R, 31 C (will take one more time)
EC’s: 21+ hours with leadership
Work: none
Also, they asked for an alternate choice of major on the application. Does the admissions office consider your alternate selection at all?
Any response or advice is much appreciated. Thanks!

You are a competitive applicant and retaking the ACT is wise since SLO superscores. SLO has accepted qualified applicants in the past few years into their alternate major so it is to your benefit to list one. ME has about a 17% expected acceptance rate and EE around 38% acceptance rate. Much will depend upon how competitive the in-coming Freshman class will be so I would put down both majors for the best chances.

Good Luck.
