I am going to be a senior this year, and I wanted to know if it is possible to raise my GPA.
Get higher grades.
Yes, definitely possible to raise your GPA but it may not be in time for college applications depending upon the school deadlines. As stated above, get better grades and study harder.
I’d like to get it to a 3.5 at least.
3.5 from what?
Is it possible for a 3.21? It should go up a bit since I just finished taking a class and got a high A.
When you apply you’ll have zero or one more semester of grades. That can’t balance out six semesters very much.
@bondievie we would need to know how many units/courses you’ve taken and how many you plan on taking your senior year.
If you got a 3.21 GPA over six semesters and get a perfect 4.0 your senior year, and if you take the same number of credits, your HS GPA should be roughly (3.213 + 41)/4 ~= 3.4.

I have a 3.5714 weighted and 3.2143 unweighted GPA for taking 21 courses.
