If you’re worried that your teen isn’t taking the college application process seriously enough, resist the urge to jump in and take it seriously for them. Instead, be honest about your concerns. Tell them how excited you are about their college future. Let them know the efforts you’ve made to save for their college tuition, and the sacrifices you’re willing to make to send them.
I’m not suggesting you say those things to make your teen feel guilty. I think a mature teen will appreciate how much emotional and financial investmenet you’re willing to make in them.
Then they might be a little more open to hearing your concerns about the looming deadlines and the lack of application action.
