Hi Matt, Hope you are well. Yes - the question is asking is X not equal to 3 and is X positive. The question is how do you get there? I'll go on record again saying that it's important for GMAT DS to think about extremes (limits), thresholds, and special numbers to focus your work. I'm not quite sur...

Hi Ganesh,
Yep - that's exactly right. Understanding critical points/Max/Min/Limits is super important for DS.

Hi Ganesh, Good question. This is a standard but tough DS question. With DS you always want to think about special numbers: 1, 0, Negative, Positive, Integers, Non-Integers, Maximum, Minimum If X is zero then this will be undefined. If X is 1 you can answer Yes. If X is negative you can answer No. I...

Hi Soumita, Great analysis on this. The reason that A is incorrect is that there can be other cookware that is superior AND at the same time customers will not be disappointed with the kitchen line. So that the Kitchen line being superior is not an assumption necessary for the conclusion to be true....

Hi Dave, You can purchase a subscription for Manhattan GMAT CAT Tests. The tests can generate reports and you can get a pretty thorough breakdown of your timing and weak areas. GMAT Club tests are also good but have fewer reporting features. One thing that you can do is keep an error log as you stud...

Hi K,
I hope that you are well. If you provide more of your work we could analyze what went wrong. Do you have a specific question on this?

Hi, I hope that your studying is going well. I have not looked at the Aristotle book (is it a strategy book or a book of RC passages?) but if you are having RC issues I would recommend reading an article every day from a well written publication (like the economist). This will help you increase your...

Hi,
I took a quick look at the Quant Review second edition but I couldn't find this question. Maybe I missed it. What number is it?

Hi, I hope you are well. Ceilidh made some great points here. The one that I would like to stress: Spend more time reading/understanding the questions than you spend contemplating answer choices. I find that the longer I spend staring at answer choices the more they all blur together. In general, th...

Hi, This a list so you should be thinking about making it parallel. Looks like it should be: The compositions are known for their X, their Y, and their Z. The their in italics is implied by the list. The compositions of Claude Debussy are known for their orchestrational subtlety and brilliance, a us...

Hi Paresh, I hope you are well. That statement does looks sufficient. We can set up a chart to illustrate the population growth. Each day the population grows at a constant rate. Let's call that X. Day Population 1 200 2 200x 3 200x^2 4 200x^3 5 200x^4 6 200x^5 7 200x^6 or 5,000 (according the state...

Hi Tommy, That makes sense about the pasting of the examples. Just to clarify. Are you saying that the construction: If I should ..... I will..... is incorrect? Or just that the correctness of the tuxedo sentence depends on how likely it is that I will attend the party? And perhaps you're right that...

Hi Tommy, That all makes sense and I agree. I'm sorry if I didn't make my point about the commas in a clearer way. What I meant was that in general you are not going to be comparing two identical sentences with the only difference being the comma placement or the absence/presence of a comma. Clearly...

Hi,
If can be used with should. If you can post the link or the article that you read that would be great. I am sure that there are times when the if/should combination is inappropriate because just as any other grammatical construction: it depends on what you are trying to express
