If you paid in 2016 for classes that you took in 2016, yes.

If you paid in 2016 for classes that were in 2015, no.

If the school "BILLED" in 2015 for classes that started in 2016, you can pay in 2015 or 2016 and take a credit in the year you paid, but if the classes were in 2015, you can only get a credit for what you paid in 2015 on your 2015 tax year return.
