Here is a bit of an update on my situation that may shed some light on this question.
In a previous thread (located HERE
) I mentioned that the automated registration had some issue and I wasn't given the option select 4 free score reports for the November exam. I contacted ETS via email and they informed me that I could use the information change stub attached to my admissions ticket in order to add these 4 schools. Due to a combination of getting my admissions/change info ticket late and procrastinating because I kept changing my mind on which schools I would send the scores to, I ended up waiting until the last moment. On the Friday before the November exam, i.e. the last day they would allow me to change my score recipients, I sent them an email with my change information. Today, the following Wednesday after the exam, they emailed me to tell me that they wouldn't allow me to select my schools because I didn't get my information in on time. Apparently what they mean by, "the Friday before the exam day" is "Before the end of standard business hours, on the Friday before the exam" so I missed the deadline by a couple of hours.
Just to be clear, I'm not complaining that ETS didn't accept my information. It is ultimately my own fault for taking too long to make my decision. What I am saying is that if they wouldn't accept my request which was only 2 hours late and partly caused by their own system, they almost certainly won't accept a change request a couple days past the deadline.
