Very Urgent... Please Help!!!!

Go through Powerscore CR to get idea about different types of questions. Don't fret too much with powerscore strategies as they are meant for LSAT. Though the question types are similar, GMAT questions are not purely logic based so it is difficult to find patterns in answer choices. Every question is unique in its own way. All you can do is practice as much to learn general structures of CR questions. Use powerscore to know the types of questions and don't use any techniques provided to categorize answer choices.

Try taking notes while answering the question. Write down the conclusion atleast as it will help you comprehend better. Read the question stem first always and then go for the stimulus. Prephase answer choices before answering any question except for inference/conclusion questions. It is quite difficult for those types of questions. Use the process of elimination while answering the questions. Write down answer choices and strike them down while solving, you save time and no need to recheck that answer choice again. Practice less review more. Always try to eliminate wrong answer choices in verbal queations instead of finding right ones. Sometimes prephased answer choices won't match the actual answer as in a real world scenario there are numerous reasons to strengthen/weaken an argument. So it is better to eliminate than to find the right ones. It will improve your accuracy to a great extent and you will get better in reasoning and understanding the questions. Hope this helps.
