At the risk of giving toxic diet advice (sorry, 90s teen years and all that!), could you push yourself to not have dinner after the late classes? Exercise does make you hungry and you're likely to eat more in those meals.
Also, probably worth tracking calories precisely. Butter, cheese and hummus can add up quickly for example.
Reason why I am saying this is when I upped my exercise, I didn't lose for a while. I then realised that I was eating bigger portions of healthy food on exercise days. It's easy to go to 1,400 when you think it's 1,000.
I realised I need quite an extreme deficit, probably -600 a day, to lose significant weight.
