@fallenchemist, that makes a lot of sense!
Yes. They expect that those they admit are taking the most rigorous courses available and doing well in them. They don’t really need to weight them if they aren’t considering many (any?) applicants who are taking easy course loads.
Additionally, not all high schools weigh courses the same and many colleges that use weighted GPA will recalculate with their own weight systems, so it would be very difficult here for anyone to predict for you possible weighted GPAs.
