For schools that don't require the PCAT...

Do they still look to see if you took it, and if you took it do they look at your score and consider it in admissions?

In other words...
Does it help to take and do well on the PCAT? (for schools that don't require it)
Does it count against you if you do poorly on the PCAT, or if you don't take the PCAT?

Or do these schools not look at or consider it at all?

Thanks in advance.
