How much does it matter the mentioned intended major at grad school in GRE registration? So far as I heard, it is required to mention intended major in graduate school during GRE registration. I am curious to know, what would someone do if he wants to apply to different grad schools for different (but somehow related) programs? For instance, he wants to apply to the grad schools A, B, C, D for the grad programs P, Q, R, S respectively. My questions are:


When registering for GRE, which one would he select as his intended major at grad school? P, Q or, R?
Would selecting the program P as his intended major at grad school, lower his opportunity to get into programs Q or, R?
If he mentions "Other fields" as his intended major at grad school (that is, he mentions that his intended grad major is undecided) then would it lower his chance of getting into grad programs P, Q and, R?
If S is an interdisciplinary grad program and it is possible to apply to the program S with background in P, would mentioning P as his intended major at grad school lower his chance to get into the program S?
I wouldn't worry about it because that portion is used for statistical purposes like compiling average test scores by major, like in the example here: http://www.ets.org/s...uide_table4.pdf 

The information that schools look at that regard majors are if you take a subject test, like in computer science or physics. And of course all of your undergrad data. 

Additionally, marking undecided is possible if you really dont want to choose one.
