Hi riteshpatnaik,
Ceilidh's explanation is spot-on, so I won't rehash any of that. Instead, I'm going to add a few examples to help prove the point:
Once we know that:
1) XY is NOT = to 0
2) X > Y
3) X^2 = Y^2
X and Y COULD be...
1 and -1, so XY = -1 and the answer to the question is NO
2 and -2, so XY = -4 and the answer to the question is NO
3 and -3, so XY = -9 and the answer to the question is NO
4 and -4, so XY = -16 and the answer to the question is NO
Etc.
Based on the pattern, XY will ALWAYS be negative, so the answer to the question is ALWAYS NO. Thus, the final answer is C
GMAT assassins aren't born, they're made,
Rich

Thanks Matt. This is exactly how I arrived at my answer. How do we get from this point to the final answer?
Thanks!

The high-speed train's rate = z/x
The low-speed train's rate = z/y
So the high-speed train travels (z/x) - (z/y), or z*(y - x) / x*y faster per hour than the low-speed train.
By the Lazy Test Writer Principle, the answer must contain some form of the numerator or the denominator. Only A does, so we're done.

Subject: My Journey from 630 to 710!
Posted: Mon Nov 28, 2016 12:20 pm (GMT -8)
Hey Guys,
I purchased the MGMAT books. I studied them for a few weeks but could not figure out what the hype was all about. I didn't think the Quant was presented in a way so that I could learn effectively. Then I stumbled upon Target Test Prep (TTP). As I had never heard of the product before, I was a little nervous about purchasing. I'm so glad they offer a free trial. After doing one or two chapters, I realized that this is the right way to study for the GMAT. The lessons are super well organized. The best part is, you don't sit through an hour of lecture just to forget the concept at the end. Each slide has a concept and if appropriate, a few questions and a few videos to help you learn that particular concept! This format makes the most sense to me.
The user interface is amazing! These guys must have used some high end web design people. I scored a 630 the first time I took the test and was disappointed as I knew that I could do better. After taking the class, I got a 710!
I highly recommend this course to everyone. I would recommend that you take advantage of the free trail, see if the course clicks with you the way it clicked with me!
PS: Compared to the other classes, this course is a bargain.

Ok, this may not be a complete list, but here's what comes to mind...
If the question is asking about:
1) MEAN
- helpful: sum, number of terms
- not helpful: median (unless it's an evenly spaced set), range (or smallest or largest value), standard deviation
2) MEDIAN
- helpful: number of terms
- maybe helpful: whether it's an odd or even number of terms
- not helpful: mean (unless evenly spaced), range (or smallest or largest value), standard deviation
3) STANDARD DEVIATION
- helpful: knowing the value of every term
- maybe helpful: range
- not helpful: anything else
4) RANGE
- helpful: smallest and largest values
- not helpful: anything else (unless evenly spaced and you know the # of terms)
5) SUM
- helpful: average and number of terms
- maybe helpful: starting or ending value (if you have # of terms)
- not helpful: median (unless evenly spaced and you know # of terms), range, standard deviation
As a very broad general rule, one statistic alone usually won't tell you much about any other statistics!

To start, the Quant section of the GMAT is only 37 questions, with an approximate ratio of PS to DS questions of about 22 to 15, an adaptive algorithm and fairly standard ratio of certain subjects tested. Working through 50 questions in the OG (either 'in a row' or randomly) guarantees you NONE of those factors. The individual questions themselves ARE realistic (they all once appeared on the Official GMAT at some time or another), but no book will be able to give you an exact set of 37 questions that will 'match up' perfectly with what you'll see on Test Day.
It would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied?
2) What materials have you used?s
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
Goals:
4) What is your goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
Rich
Studies:
1) How long have you studied?
I haven't studied much. I checked out a crack the GMAT book from the library a little over a year ago but haven't studied since.
2) What materials have you used?s
I recently obtained a copy of the GMAT OG 2017 and the 2016 quant review.
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)? I took the first on on 11/25. Scored 570 43 quant 25 verbal. Disappointed in both but I ran out of time on the quant so had to guess on the last 3 questions and when reviewing I knew them. Most of my mistakes were simple comprehension. Answering how many when the prompt asked for what was left, etc.
Goals:
4) What is your goal score?
I would like to obtain 700 to keep my options over.
5) When are you planning to take the GMAT?
No definite time table yet but around spring 2017
6) When are you planning to apply to Business School?
Looking to start Fall 2017
7) What Schools are you planning to apply to?
With work and a family, my choices are somewhat limited compared to where I would like to go. ![Smile]()

Hi jbryant62,
To start, a 570 is a solid initial CAT score (the average score on the Official GMAT hovers around 540-550 most years). With the timeframe that you've described, you have plenty of time to study and improve, which is good. You'll want to come up with a study routine that you can consistently follow though, because the time will pass by faster than you think it will. I suggest you study as you see fit for the next 2 weeks, then take a new, FULL-LENGTH CAT (with the Essay and IR sections). Once you have that score result, you should post back here. That score will give us a better sense of how well your current studies are going, as well as how you might adjust them going forward.

Rich

Definitely NOT.
That way of eliminating answer choices is WAY TOO SIMPLISTIC for consistently getting CR questions right.
The conclusion is that ground based telescopes will become obsolete. There could be about some specific telescope or subgroup of telescopes a fact that weakens the conclusion.
In fact, the OA talks about a very specific use of telescopes. So by a similar logic, maybe E would be eliminated.
In fact, from what I have seen, in doing CR questions, eliminating the OA first, yup, FIRST, is something people often do. Why? Because they attempt to use simplistic methods to get the right answer to CR questions, and in many cases the simplistic methods filter out the OA, leaving people with four wrong answers to choose from.
So overall, the message I want to give you is to dispense with the idea that the way to rock in CR is to come up with a bunch of formulaic ways to get to answers. The way to rock in CR is to use high level thinking to actually see and analyze exactly what is going on.
Why bother with some thing like "This answer choice is too specific." "This answer choice talks about X, while the conclusion is about Y." or "This answer choice is extreme."?
Those ideas, and even "out of scope", tend to be cop outs or half measures.
Hey, if you want to get some right answers with some minimal prep, sure use those things, but gocoder, you are working at this for real, training hard. So take it to the next level. If you are going to work on something, work on seeing what's going on in the questions for real.
You can prove each wrong answer wrong, for real.
You can prove the right answer right, for real.
Here's what I mean.
(A) The fact that a single space based telescope is over budget does not change the dynamic described in the prompt, that spaced based telescopes provide better images, and therefore ground based telescopes will become obsolete.
(B) This does not change the fact that space based telescopes provide better images.
(C) Avoiding most of the distortion does not mean avoiding all of the distortion. Space based telescopes still provide better images, and this does not weaken a conclusion based on that fact.
(D) This is irrelevant. The argument is based on a key difference between space based telescopes and Earth based telescopes. The fact that a certain way of using Earth based telescopes is the best way to use Earth based telescopes does not affect the connection between the better images provided by space based telescopes and the expected obsolescence of Earth based, or ground based, telescopes.
(E) Ok. Here you have it. Since ground based telescopes can do something key that space based telescopes cannot do, the idea that ground based telescopes will become obsolete does not currently make sense.
No rules. No formulaic methods. Just straight up logic. Always works. Never fails.
If you want to really ROCK at CR, focus on learning to use vision and logic.

Subject: The STAR Approach When Writing MBA Application Essays
Posted: Mon Nov 28, 2016 11:20 pm (GMT -8)
![]()
The STAR (Situation, Task, Action, Result) approach is one of the most basic and versatile structures that an applicant can use to frame answers to your application essays. Once you have picked an appropriate story that you want to tell, this approach helps you draw the story out in a compelling way, and also helps you stick to the required word count.
When should you use this approach? The answer is simple. It is whenever a question is asking you to share a specific experience, whether it is your greatest memory or challenge, a time when you showed leadership, or a recent accomplishment.
These are the main sections of the STAR approach:
1. Situation: This section is where you succinctly set up the context for the essay. This is where you outline the stakes, or where you share the watershed encounter that led to your subsequent actions, impact and learning. For instance, if you are telling a story where the question asks you to describe a time when you received professional feedback and how you responded to it, you could start your essay with the specific quote your supervisor used when sharing this feedback with you. You need to ensure that you do not spend too much time or space in the essay on this section, especially when you have a limited word count. The context should be concise, clear and punchy.
2. Task: This section is where you describe the specific task that is in front of you, based on the context that you have previously set up. Again, the task ahead should be one specific task that you are addressing â like executing on the feedback that you received from your supervisor, or meeting a challenging, high-stakes deadline with minimal resources. The context is already set up, here you are just clearly, and in one line really, stating the specific challenge that lies ahead.
3. Action: This section is where you often end up spending a significant proportion of your time and word count real estate in the essay. The main premise of this section is to describe how you went about executing your task. The mistake that is often made is when you share a series of statements stating what you did, without explaining exactly how you did it. For instance, if you are describing a time when you led a team to close a deal, you need to talk about how you negotiated with the client, how you empowered your team to take responsibilities, etc. By explaining how you did what you did, you are demonstrating your ability to execute.
4. Result: This section is where you state the impact of your actions in the context of your task. Did you close a multi-million-dollar deal, or win a national award? This is where you would state the result you have achieved for the organization or institution, or your inability to do so, if the question asked is focused on describing a failed endeavor. This section should also use minimal word count, be clear and punchy.
5. Learning: This section is often the most critical section in the essay, especially in questions which ask you to share how you have grown personally and professionally, or specifically state that you need to share what you have learned. It reflects your mindfulness and self-awareness, and the depth and quality of your insights. This is the space in the essay where you have an impactful answer to the question, why? Why is the impact you made significant not just to the organization, but to you?
It is extremely important to understand:
* the nuances in the questions, and to then accordingly give word count weight age to the sections described above so that you are clearly answering the question and not force-fitting a story.
* how to stylize the answer â you need to be able to tread that fine balance between authenticity and sharing a powerful, passionate story that is not disingenuously hyperbolic.

I am a recent year graduate from the same course. Given the fees and hardwork you put on the course the outcomes are not worth. The college has got no reputation among corporates in all the three cities as such, especially in Singapore and Sydney. Even in India nobody bothers if you have done Global MBA unless corporate relations team makes some good relationship, on which the college goes down under. Our batch and other batches too faced severe issues in placements and the behaviour of corporate relations team is really rude. They will stop responding to you after you finish the course and leave the campus unplaced. No doubt some of the faculties are world-class but at the end it's the platform the college can offer you in the corporate world which matters. I am here to give the right comments on what we faced as the batch, as well as other batches in the same course of time. My advice would be to get into some decent university abroad if you really want to study abroad rather than going for this. Lot of us felt that we took a hasty decision for pursuing international education with this college.

Top 5 Tips To Keep In Mind When Choosing Your Stream
Once you have completed 10th grade, it is always a tough call to choose an academic stream that suits you best. When I was making this choice, I remember being really confused and senile. I loved physics, which is why I was inclined towards Science, I wanted to pursue journalism in the future which meant I should go for Humanities, and my parents advised me to opt for Biology and become a doctor! I fretted for a few months, changed my mind a couple of times, before I finally decided to take physics, chemistry and math.
I am glad that I thought this through before I made a final choice, as a lot of students end up selecting a stream that does not align with their goals and interests.
