How many AP Exams should I report on common app?

common app has a section titled "AP Subject Tests" and it asks "Number of AP Tests you wish to report, including tests you expect to take." I'm a senior and I am taking 7 APs, if I don't take all 7, should i still include in that section that i'm still taking those exams? Will they check? In collegeboard i initially registered for all 7 exams, so worst case I can say sum like i forgot changing it or like i thought it meant all APs i took. Wdyt i should do?
