It depends.
Some recalculate GPA; some take the GPA that is listed on the transcript. Some count freshman year; some don’t. Some back out music/art/gym; some don’t.
File it under “It is what it is” since few colleges will explicitly tell you the policies.
On an unweighted GPA, it means no grade lower than an A. Each HS will determine that numerical cutoff. For some, it’s a 90; for others it’s a 93.
