Just for the analogy, they are not hard or complicated words, they are everyday ones and you need to find the relationship between them. The key word is "relationsip" e.g how does table and chair relate to each other, then they give you a word and you have to find another word the relates same way!!!!! Trying to study vocab is a big waste of your time!!!! in the sentence completion you need to know wat certain words mean and fill in the blank. But the key thing is to understand the sentence and know what kind of word is missing there!!!!!!!!!! Pcat is definitely not rocket science, the designed it to weed out people, it is not hard at all!!! But you need to study a lot!!!!!!!!!!!
