Carcass thanks a lot for clarifying. The biggest problem I'm encountering is that because a lot of people here are recommending me to stick to the official material, i.e. only ETS material, I am running out of new verbal questions to do and I feel at this point I'll end up memorizing them instead of understanding my mistakes. Different material vary from the actual paper and that's why I'm restraining using from them but what am I to do if I kind of "remembered" all the text completion questions given in official GRE material?
