I have already taken the General GRE and am taking the Physics subject test in a week. I am struggling to figure out how the billing system of sending scores work before I decide to pick my four schools that I can send my scores to for free. ETS' website says that it is $27 per score recipient. This, to me, implies that if I send both my general and subject scores at the same time (assuming it's possible for me to do so), I can save some money. That being said, is that how it actually works? Or must I send my scores separately and pay $27 to send my general score and then $27 to send my subject test score? I am asking so I can optimize who I send my scores to for my subject test. Would it be better for me to pick the same schools I did for the General GRE (I would love to do this; I'm just worried it may not be the smartest financial option)?
