Let's cover some background here.

My dad is quite religious, while my mom is not. They are divorced, so I spend my week during my mom's and weekend at my dad's. 

My dad has always been quite religious since I remember. When I told him I wasn't really interested in being all that religious, he wasn't happy. I just switched this year from a religious private school to a public school (which has so far been a great change for me). Problem is, religious holidays are coming up soon that would require me to take off school. I can't afford to do that because I would have to miss four days of class, and I'm in a college-course curriculum. That's a lot of material I don't want to make up.

I'll be staying by my mom during the holiday, but my Dad wants me to stay by him. If I tell him I'm going into school, he'll blow a fit. He doesn't even allow me to eat school lunch because it's not up to religious par. My question is do I just keep silent about it? Do I ask my mom to get involved? She communicates with him frequently. I'm just at a loss.

Dad wants me to stay out of school for religious holidays. I can't afford to do that. I'm stuck between a rock and a hard place.
