Post-submission nerves

Hey y’all. I submitted my applications for R2 and have been having very anxious thoughts, thinking if I made any stupid application mistakes.

I’m an international applicant from Germany. Our grading system is reversed, where 1.0 is the best grade and 5.0 is the worst. My GPA is 1.5, which is roughly equivalent to a 3.7 in the US system. Wherever possible, I indicated the grading scale. Now I’m overthinking and worried that the adcom might read it wrong.

Did anyone navigate such a situation?
