good job, well done

get rid of Barron, that's a waste. Kaplan + OG will help. good luck

Dude, I don't think you need to re-take the test. I got 730 but I kept scoring 770-780 during practice, Did I re-take it? No, there is no need to do so, unless you just want to make yourself happy. I understand your frustration by getting the score lower than expected, but we have to understand what is more important after the test. To me, any score above 700 is awesome, and it's good enough for any B-school. Re-taking GMAT when you have such a high score won't prove that you are competitive, but that you are just stubborn. Like someone mentioned above, as a MBA, you have to differentiate what is more important and yield better returns. You have done the test, dude, the most important thing for you is your application and essay!!! Good luck

1. If 4 books are to be selected randomly from 2 hardback books and 6 paperback books, what is the probability that one of them is a hardback book? 2. Set A contains positive integers from 101 to 500, inclusive. What is the probability that a number N, which first digit is 1,2, or 3 and last digit is 4, 5, or 6, can be selected randomly? 3. Is line y=2x+3 passes through point (r, s)? 1) (2r-s+3)*(4r+2s-6)=0 2) (3r+2s-5)*(2r-s+3)=0 Please share your thoughts, thanks

Please explain. Thanks

Edwina: True appreciation of Mozart’s music demands that you hear it exactly as he intended it to be heard; that is, exactly as he heard it. Since he heard it on eighteenth-century instruments, it follows that so should we. Alberto: But what makes you think that Mozart ever heard his music played as he had intended it to be played? After all, Mozart was writing at a time when the performer was expected, as a matter of course, not just to interpret but to modify the written score. Alberto adopts which one of the following strategies in criticizing Edwina’s position? (A) He appeals to an academic authority in order to challenge the factual basis of her conclusion. (B) He attacks her judgment by suggesting that she does not recognize the importance of the performer’s creativity to the audience’s appreciation of a musical composition. © He defends a competing view of musical authenticity. (D) He attacks the logic of her argument by suggesting that the conclusion she draws does not follow from the premises she sets forth. (E) He offers a reason to believe that one of the premises of her argument is false.

OA is B. GMAT168, please provide some explanation when you feel better. thanks

In clinical trials of new medicines, half of the subjects receive the drug being tested and half receive a physiologically inert substance—a placebo. Trials are designed with the intention that neither subjects nor experimenters will find out which subjects are actually being given the drug being tested. However, this intention is frequently frustrated because______ Which one of the following, if true, most appropriately completes the explanation? (A) often the subjects who receive the drug being tested develop symptoms that the experimenters recognize as side effects of the physiologically active drug (B) subjects who believe they are receiving the drug being tested often display improvements in their conditions regardless of whether what is administered to them is physiologically active or not © in general, when the trial is intended to establish the experimental drug’s safety rather than its effectiveness, all of the subjects are healthy (D) when a trial runs a long time, few of the experimenters will work on it from inception to conclusion (E) the people who are subjects for clinical trials must, by law, be volunteers and must be informed of the possibility that they will receive a placebo

It takes 365.25 days for the Earth to make one complete revolution around the sun. Long-standing convention makes a year 365 days long, with an extra day added every fourth year, and the year is divided into 52 seven-day weeks. But since 52 times 7 is only 364, anniversaries do not fall on the same day of the week each year. Many scheduling problems could be avoided if the last day of each year and an additional day every fourth year belonged to no week, so that January 1 would be a Sunday every year. The proposal above, once put into effect, would be most likely to result in continued scheduling conflicts for which one of the following groups? (A) people who have birthdays or other anniversaries on December 30 or 31 (B) employed people whose strict religious observances require that they refrain from working every seventh day © school systems that require students to attend classes a specific number of days each year (D) employed people who have three-day breaks from work when holidays are celebrated on Mondays or Fridays (E) people who have to plan events several years before those events occur

Graphologists claim that it is possible to detect permanent character traits by examining people’s handwriting. For example, a strong cross on the “t” is supposed to denote enthusiasm. Obviously, however, with practice and perseverance people can alter their handwriting to include this feature. So it seems that graphologists must hold that permanent character traits can be changed. The argument against graphology proceeds by (A) citing apparently incontestable evidence that leads to absurd consequences when conjoined with the view in question (B) demonstrating that an apparently controversial and interesting claim is really just a platitude © arguing that a particular technique of analysis can never be effective when the people analyzed know that it is being used (D) showing that proponents of the view have no theoretical justification for the view (E) attacking a technique by arguing that what the technique is supposed to detect can be detected quite readily without it

thanks

you are right, I didn't even notice that He is the policy advisor, so that's self-interest.

Finally got you on the first one :D :D the OA is C, and I initially pick A. I totally don't understand the "self-interest" in C, do you have any thoughts? for the second question, OA is D

GMAT168, I see where I get messed up. in C, it's "effective ways to USE energy", but I read as "Store energy", so actually C is out of scope, isn't it?

GMAT168, you are right, the OA is B, but would you refute C for me? My reasoning to pick C is as follows: In the stem, the reviewer states "However, I cannot call to mind any affective ways to store energy as electricity", this means the reviewer believes that the basic ways and the effective ways to store energy are related. In addition, the reviewer states "whereas any capable student of physics could readily suggest a few more ways to store energy: chemical, gravitational, nuclear", this means he believes if we treat basic ways to store energy unrelated to the effective ways, we can name as many alternatives as we could. thanks

From a book review: The authors blithely claim that there are “three basic ways to store energy: as heat, as electricity or as kinetic energy.” However, I cannot call to mind any affective ways to store energy as electricity, whereas any capable student of physics could readily suggest a few more ways to store energy: chemical, gravitational, nuclear. The reviewer makes which one of the following criticisms of a claim that appears in the book under review? (A) There is no reason to consider any particular way to store energy any more basic than any other. (B) The list given of ways to store energy is possibly inaccurate and certainly not exhaustive. © It is overly limiting to treat basic ways to store energy as a question unrelated to the question of effective ways to use energy. (D) What needs to be considered is not whether various ways to store energy are basic but whether they are effective. (E) Except possibly for electricity, all ways to store energy are equally effective and therefore equally basic.

Policy Adviser: Freedom of speech is not only a basic human right; it is also the only rational policy for this government to adopt. When ideas are openly aired, good idea flourish, silly proposals are easily recognized as such, and dangerous ideas can be responded to by rational argument. Nothing is ever gained by forcing citizens to disseminate their thoughts in secret. The policy adviser’s method of persuasion, in recommending a policy of free speech to the government, is best described by which one of the following? (A) a circular justification of the idea of free speech as an idea that flourishes when free speech is allowed (B) advocating respect for basic rights of citizens for its own sake © a coupling of moral ideals with self-interest (D) a warning about the difficulty of suppressing the truth (E) a description of an ideal situation that cannot realistically be achieved Which one of the following, if true, world most strengthen the argument? (A) Most citizens would tolerate some limits on freedom of speech. (B) With or without a policy of freedom of speech, governments respond to dangerous ideas irrationally. © Freedom of religion and freedom of assembly are also basic human rights that governments must recognize. (D) Governments are less likely to be overthrown if they openly adopt a policy allowing freedom of speech. (E) Great ideas have flourished in societies that repress free speech as often as in those that permit it. Please explain, GMAT168, I am waiting for your explanation

GMAT168 is right, the OA is E

OA is E. Would you guys provide some explanation why pick E?

Book Review: When I read a novel set in a city I know well, I must see that the writer knows the city as well as I do if I am to take that writer seriously. If the writer is faking, I know immediately and do not trust the writer. When a novelist demonstrates the required knowledge, I trust the story teller, so I trust the tale. This trust increases my enjoyment of a good novel. Peter Lee’s second novel is set in San Francisco, in this novel, as in his first, Lee passes my test with flying colors. Which one of the following can be properly inferred from the passage? (A) The book reviewer enjoys virtually any novel written by a novelist whom she trusts. (B) If the book reviewer trusts the novelist as a storyteller, the novel in question must be set in a city the book reviewer knows well. © Peter Lee’s first novel was set in San Francisco. (D) The book reviewer does not trust any novel set in a city that she does not know well. (E) The book reviewer does not believe that she knows San Francisco better than Peter Lee does.

Whenever a major political scandal erupts before an election and voters blame the scandal on all parties about equally, virtually all incumbents, from whatever party, seeking reelection are returned to office. However, when voters blame such a scandal on only one party, incumbents from that party are likely to be defeated by challengers from other parties. The proportion of incumbents who seek reelection is high and remarkably constant from election to election. If the voters’ reactions are guided by a principle, which one of the following principles would best account for the contrast in reactions described above? (A) Whenever one incumbent is responsible for one major political scandal and another incumbent is responsible for another, the consequences for the two incumbents should be the same. (B) When a major political scandal is blamed on incumbents from all parties, that judgment is more accurate than any judgment that incumbents from only on party are to blame. © Incumbents who are rightly blamed for a major political scandal should not seek reelection, but if they do, they should not be returned to office. (D) Major political scandals can practically always be blamed on incumbents, but whether those incumbents should be voted out of office depends on who their challengers are. (E) When major political scandals are less the responsibility of individual incumbents than of the parties to which they belong, whatever party was responsible must be penalized when possible.

My bad, OA is A. I edited my original post.

Not all tenured faculty are full professors. Therefore, although every faculty member in the linguistics department has tenure, it must be the case that not all of the faculty members in the linguistics department are full professors. The flawed pattern of reasoning exhibited by the argument above is most similar to that exhibited by which one of the following? (A) Although all modern office towers are climate-controlled buildings, not all office buildings are climate-controlled. Therefore, it must be the case that not all office buildings are modern office towers. (B) All municipal hospital buildings are massive, but not all municipal hospital buildings are forbidding in appearance. Therefore, massive buildings need not present a forbidding appearance. © Although some buildings designed by famous architects are not well proportioned, all government buildings are designed by famous architects. Therefore, some government buildings are not well proportioned. (D) Not all public buildings are well designed, but some poorly designed public buildings were originally intended for private use. Therefore, the poorly designed public buildings were all originally designed for private use. (E) Although some cathedrals are not built of stone, every cathedral is impressive. Therefore, buildings can be impressive even though they are not built of stone.

yaa, OA is A

A careful review of hospital fatalities due to anesthesia during the last 20 years indicates that the most significant safety improvements resulted from better training of anesthetists. Equipment that monitors a patient’s oxygen and carbon dioxide levels was not available in most operating rooms during the period under review. Therefore, the increased use of such monitoring equipment in operating rooms will not significantly cut fatalities due to anesthesia. A flaw in the argument is that (A) the evidence cited to show that one factor led to a certain result is not sufficient to show that a second factor will not also lead to that result (B) the reasons given in support of the conclusion presuppose the truth of that conclusion © the evidence cited to show that a certain factor was absent when a certain result occurred does not show that the absence of that factor caused that result (D) the evidence cited in support of the conclusion is inconsistent with other information that is provided (E) the reason indicated for the claim that one event caused a second more strongly supports the claim that both events were independent effects of a third event
