GPA

Is 3.68 weighted gpa bad for sophomore year? I intend to bring it up junior year. Also do colleges see an average of all three years of gpa or just junior year gpa?

Depends on the college you are applying to, 3.68 may be sufficient or lacking.
A decent GPA for top universities would be around 3.8-3.9.
On your Common App, you put in your cumulative GPA but since the universities have your transcript, they will also look for things such as trend, course rigor, etc.
Remember though, there are a lot more to you and your college app than numbers.
Work hard in school, exams and your ECs, then I’m sure you’ll be fine.
Good Luck!

I intend to bring it up to 3.8 or at least 3.7 next year. I’m looking to apply to good schools although not Ivy leagues or top universities. I still have time to bring it up right? Thank you for your help.
