Transfer credit grades (from dual enrollment) used towards college GPA?

Just going to mention that this used to be common. I think changing the cut off to a 90 for an A has coincided with a general trend towards grade inflation. When I was in high school and college, it was most common for a 93 to be the cutoff for an A. Then 93-90 was in the B+/B range.

Can only speak to my state of California…Dual credit grades are used in calculating GPA for admission purposes, but once you matriculate, you only get the credits and the grades are NOT part of you college GPA at that university (although they will go into college GPA if you apply for grad school, med school, law school, etc.). So seems UNcommon to me.
