I think I remember reading in this community that you can just skip the sections you don't want to retake, but how sure are you that this can be done without repercussions? Will the proctor think it's weird that you leave so early?
(I called ETS, but the conversation went something like this:
Me: I was just wondering, can you retake just one section of the GRE? I heard that you can just skip the sections you don't want...
Rep: We do not [something] tell you that. You can only find out on the day of your test. [something about disclosure and a whole bunch of stuff about canceling scores, confirming score cancellations, etc., none of which seems relevant]
Me: So...there isn't a way to retake a specific section?
Rep: Well, yes, there is, and there will be instructions on the screen. It will always give you the option of exiting sections.
Me: Huh? What's the difference between that and what I just said about skipping sections?
Rep: [Repeats what she said earlier]
It might just be a non-disclosure and/or semantic issue, I guess.)
