Did I Just Ruin my Chances of getting into college?

So I recently got a 72 on my Physics mid-term. I’m basically freaking out that I just ruined my GPA because midterms and finals account for 1/6 of my final grade. So any advice on making sure it will not ruin my GPA or at least improve it to keep my GPA above a 3.00?

How is your grade in the class before this grade?

My 1st quarter grade was an 84 then 2nd quarter i feel like i did good after the progress report so i am guessing mid to high 90s
