This feels so silly but I sent over an email to one of the law schools which I applied to early (due date is next week). Since I am retaking the February test, this was an email notification letting them know that I am sitting for Feb. They responded that they will note it and take the Feb test into consideration if they find it appropriate. It was a short response (1-2 sentences) that I am sure they send a lot of in general. I responded last night with a thank you email and this morning I got sent a variation of their first response, so clearly it's not a robot responding but I'm sure they have some standard boiler-plate response they email out.
Do I respond back with another thank you? Point out that this was already sent to me? This feels so silly but obviously I wasn't expecting to have to respond again.
