There is one floating in this forum but it has close to 2000 words! It is here in the forum.
it also has a huge vocab list that is gmat focused.
I tried going through the words but honestly its very frustrating, boring and unnecessary. Mostly all critical words that you might encounter would be known to you. I have yet to come across a word in any test/material whose meaning I needed/wanted to know!
P.S. My vocab isn't that great.
What you can do is - When you read passages/sentences and you come across a word you do not know - immediately look it up in a dictionary. Only then will the word cement in your mind forever!
Thanks Akhilesh, for sharing the link. Seems like they have copy pasted the entire Barron's wordlist. I went through 50% of this list about 6-7 years ago when I planned to give my GRE, which I never gave
But unless you give GRE these words won't cement, or unless you intentionally try to use them everyday; now I regret for not giving GRE, not just for GMAT but in general, as it's good to have this wordlist in your arsenal - anyways, whatever!
Currently, that's what I have been doing: if I come across a difficult word that I vaguely know but not 100% sure, I take a note of the word. I was just wondering if there is a short 'n' sweet (:p) comprehensive list of frequently used words in GMAT floating somewhere.
