Sorry I had somehow registered 360+ 420 :(. But, yes, 850-> 1000 is a doable goal to have. (1000 means “college ready” and “average”, whereas 850 means the opposite. You sound smart and mature, there are no reason why you can’t get a 1000 if you practice beforehand. The prep videos on Khan Academy are excellent and should help you.)
Call them ASAP. (Isn’t your FA package on your portal already?)
Did you apply Temple Option to Temple? Because honors scholarships will be based on your essays for that.
