Hi Sarthak, Congrats on your score! That's amazing. I scored a 660 in my first attempt and need to cross that 700 mark. One question- would you mind sharing the excel file that you maintained to track your progress. It would really help me get an idea of how exactly to track proglems. Also, did you ...

In this question, what I do not understand from the explanation is the following: 1. If x < -1, the values inside the absolute value symbols on both sides of the equation are negative, so we must multiply each through by -1 (to find its opposite, or positive, value): |x + 1| = 2|x -1| -(x + 1) = ...

A question on the phrase 'increasing rate'. Is this used correctly in the answer choices? The correct answer choice (A) does not use the word 'increasing' when talking about the rate. Thanks!

Thanks, Tim. I should have added this to my initial post: plugging in numbers in both formulas doesn't give me the same answer. The correct answer is 2. Using Formula 1, I get x=2, if action-drama-comedies are x. # of items total = (a + b + c) - (ab + ac + bc) + (abc) 38 = (10+20+18) - (5+3+4) + x 3...

I eliminated choices (A) and (B) based on this: 'prevented from...' suggests that the sound itself is being prevented from something. However, its the acoustic energy that is prevented from dissipating. Is this reasoning right? All the talk of auxillary verbs, absolute phrases and other things that ...

Hi, I picked D as the answer as I thought the conclusion of the argument is that utility companies expect to use renewable forms of energy at a lower cost.
