@Glennn,
Grammar I guess okay and yes Glenn thanks, but somehow "aren't they always" pops into mind as if it goes without sayin'
So of course I consulted BH, much smarter than I, and she responded, "But what about the three-year stint or even six," implying of course context in which the subject had been considering another sort of sked
"A comparison made between the success of those doing three years compared with the usual stint showed the latter far more successful. Therefore, my four years as an undergraduate did indeed prove essential for graduate school"
"Preparation" seeming to me at least, redundant, while "as an undergraduate" also seems redundant
Help, help the resta you guys
