Hello, I am a current freshman at a reasonably good, sends 5-10 kids of the 80 per year to top 20 colleges. I changed schools a couple of times from grades 1-8 and for the school I attended from 7-8 was basically a joke, it was underfunded, the teachers were pretty vocal about their disinterest in their “career” and for the last half of the year the was no dedicated math/english/history teacher. When I ended my freshman year of high school my GPA was 2.9(with all honors), second semester I was able to adjust and should be looking at a weighted gpa of 3.95 - 4.1 after finals. I know some schools such as Stanford and Princeton recalculate your GPA without the freshman year.
I want to know if schools such as MIT, Caltech or Carnegie Melon do the same thing and if not how badly my first semester GPA will mess me up. I will be in almost all APs and am able to take my math classes at UPenn starting summer after sophomore year, will this make up for a lower GPA?
