Vocabulary words not present AT ALL in exam

So one of my friends who recently gave the exam said that they completed the Vocab Mountain, and still got a very low score in GRE, the reason being that nearly none of the words came from this vocab mountain. What are the alternate sources/ ways to strengthen the vocabulary? Kindly help lol

Not saying they are wrong, but “none of the words” is a bit hard to believe. However you can explore vocab lists from other companies like Magoosh etc

It is not none, but nearly none, that’s the issue; he scored only 146 in verbal, which is a really bad score considering the preparation he put in
that’s why I want alternate sources
