Question about hours

I was looking over my application and I realized I put 25 hours/20 weeks for my job. I worked 36 hours a week over the summer and for the rest 8 weeks during the school year I worked about 12 hours. In my application, I averaged the hours, but I’m not sure if it would be too unbelievable since 25 hours during the school year is A LOT. Should I contact schools to clarify or should I assume they know I averaged the hours?

Don’t contact them, it’s a bit trivial. 8 hours during the school year is still impressive.

I have the same problem.
