I'm a junior and I was just wondering because my weighted GPA looks much, much more impressive!
99.9% of colleges look at your unweighted GPA.
The reason for that is that almost every high school calculates weighted GPAs differently.
Some HS students have a 4.00 UWGPA and a 4.00 WGPA or a 4.5 WGPA or 5.75 WGPA even though they take the same classes.
Sticking to a UWGPA allows all college admissions offices to compare and contrast applicants from all over the country and International students as well.
So if you are trying to get into an elite or IVY college you will still need to get your UWGPA up to say the 3.85-3.95 range to be considered.
Good luck.
To keep this community safe and supportive:
A small addendum is that some schools will just recalculate your GPA to their system like UCs while some schools (usually less selective schools that are likely public) will consider either but default to UW.
