Simply said: put into the trash that material.
Thank you for your prompt responses!! Then which source should I rely on to practice? I have finished OG12
and want to save questions from Verbal review 2 for last. My intended approach now is to practice by topic (comparison, parallelism, modifier...). For each topic, I will search related questions from GMAT club and choose those from sources like Manhattan, Veritas
, the Economist
, ... to practice. After I feel that my accuracy is better, I will continue with OG. I have 4 week before test date and spend about 3 hours per day to follow this approach.
How do you think? Could you please suggest other approach that is workable?
Thank you so much!
