Do first semester senior grades go into the GPA colleges look at for regular decision?

My average isn’t that high it’s a 89 right now, but I’m doing extremely well for first semester senior year and I know I can pull my GPA up to at least a 90. But I don’t know if the average colleges see for regular decision will include my first semester senior year grades.

They certainly look at the grades although I’m not sure if most schools recalculate the GPA.

Absolutely – it’s 1/7th of your HS accomplishment. Very predictive of your chances of success at their school
