Question time

So, two weeks ago I got an email from Vic's dance teacher stating that her class would now be 5-8 Mondays and Thursdays. I asked to change my schedule at work in order to get Vic to class in time. It was approved, luckily I have an understanding boss. My schedule changed from 7-4:30 Monday-Thursday and 7-11 on Fridays to 7-4 Mondays and Thursdays and 7-12 on Fridays to make up the lost hour.

My question is, should I just leave my schedule as is, or change it back?
