how is the ACT rounded?

So, I’ve been doing practice tests for the upcoming September ACT and I’m wondering how rounding works with the ACT . For example, if I receive a 29.75, does it round to a 30? does a 30.50 round to a 31? Or does it drop down, even if it’s a .50 or .75?

.5 and .75 round up and .25 rounds down.
