How important are 1st semester GPAs?

I’m a senior waiting for reply from colleges. They’re ivy leagues (UPenn, Columbia, Cornell)
Here are my GPAs from my high school life. What are my chances so far? And, how important are 1st semester GPA? (cuz my sophomore 1st sem was shit)
Freshman:
1st sem: 3.6
2nd sem. 3.8

Sophomore:
1st sem: 3.4
2nd sem: 3.78

Junior:
1st sem: 3.78
2nd sem: 4.07

Senior:
1st sem: 4.10

Is this weighted or unweighted?

@sadiea5252‌ You can’t have an unweighted of more than 4.0
and
OP, how is 1st semester any more/less important than 2nd (besides senior…)? What are your test scores?

Well I’m pretty sure they look at your cumulative gpa for the year and not separately by semester.

@Anish14‌ my first sat score was around 1825 and then my second one was around 2150.
@sadiea5252‌ my counselor told me that they’re going to send semester GPAs and colleges actually look at that.
