I'm going to make my son pay for his college applications
Are you sure you can make him pay the fees for his college applications?
I'm pretty sure I can make him to pay for those applications and he needs to pay his own way.
You should try to help your son as much as possible. College applications are not very expensive, and you could end up discouraging him from applying to where he wants to apply if he feels constrained financially.
What do you know about sending kids to college?
I know that your child will greatly appreciate any help he can get. Going to college is a big deal, and you should want him to pick the best one for him.
