Vocabulary Question

I am on Greg 2months plan, and currently on day 14 of the vocab mountain. I know the meaning of all the words till group 14, but when I take vocab quiz, for instance-group1, I come across many many new words, synonyms that are new to me and my score falls. What am I doing wrong can someone explain to me? What should be my approach to counter it?

That is what you should be prepare for because in GRE you’re ought to encounter new words . Thus, you can’t fully relay on vocab alone and that where strategies comes into play
