@FakeName1332 no not associated to CalTech whatsoever though I am quite familiar with the campus and program. My kid is about to attend Cal (UC-Berkeley) and fly the coop in 2 weeks.
Very few people have a chance at CalTech. Especially for Engineering, CS and Math. I personally know not one but 3 people in the last 2 years who got accepted to Stanford or MIT but didn’t get into CalTech. People with near perfect scores and perfect GPA. The ones I know who got in are majors like Geology and Economics.
