Forgot to list future AP tests

Something tells me this may actually be pretty trivial, but as the title says, I didn’t list on Common App the AP tests I plan to take at the end of senior year. Will they assume that I’m really not taking them and just slacking off now?

To be honest, I don’t think they’ll care too much, but if you want to be safe, maybe you should try sending them a quick (polite) update noting that you made a mistake and that you actually will be taking the exams. It can’t hurt.
