I paid for summer's tuition fees on Saturday through my bank's online service, which I assume will mean that the money will go to my 'account statement', not directly to the payment. However, a note on one of mac's payment options says that this method takes 3-5 business days to complete. I have until Tuesday (May 1) to pay this amount.

Will I be charged (interest) for a late payment?

The money might show up and I will definitely be able to pay one to three days after the payment deadline, but will I be charged anything for those late dates?

Thanks!

call the financial services at mac, they will tell you everything you need to know about your account!
