Dear Brett, The video has not only taught me a great deal about thinking style but also it has shown me ways to plan and to speed up techniques in order to efficiently arrive at the correct answer. Indeed, picking numbers is an interesting way to solve difficult word problem in variables rather than applying algebra directly as at times the problem becomes very hard with more than three variables and a small mistake in the formulation of equation may lead to wrong answer. Thanks a lot.

That's amazing! Very helpfull!!!

Eye balling is a brilliant move. Am not too good with formulae and all but am pretty good with intelligent guessing, and this strategy really takes the cake considering Geometry has a lot to do with formulae.

i have to say strategy 1 and 2 is what we all learned during high school and is basically the cornerstone of solving any algebraic equations. But bc this is a gmat, I would say the last one is the most helpful as we are conditioned to solve problems by showing the work during highschool but on the gmat, the points only goes towards the right answer not the work.

It's funny, after all the months of content studying I have committed myself to, I could never figure out why I have been making the same mistakes. Strategy! I always flounder to solve because I think I can solve; I know I can solve. Your approach, one that I have been familiar with in many encounters, was expressed in a way that I can actually adopt to save time. Thank you! Also, for the question on criteria 2, 13:00 minutes in, L=10, X=5, J=5, Y=15 shows both A or E could be correct. Readjusting the answers allowed me to confirm A.You hint at this possibility, but I figure I'd mention it.

Yeah, the eyeballing strategy won't always get you down to exactly one clearly right answer. Sometimes it does, but sometimes it only gets you in the ballpark. Still, in cases where you may not remember how to do the actual geometry, getting down to a 50-50 guess is a lot better than 1 out of 5.

Bret, thanks for uploading these videos. They are really informative. I want to ask you that as far as the verbal section is concerned, the reading comp. questions reduce my overall speed in the section. Can you suggest some strategies to deal with that in order to maximize my score?

@dominatethegmat

9 жыл бұрын

First of all, things should still average out if you treat reading comp correctly. What I mean by that is, imagine you have four questions on the quant section. In theory, it should take you about 8 minutes to answer those 4 questions (~2min per question). On reading comp, it should still take you about 8 minutes to answer 4 questions, it's just that the distribution is different. It may take you 5 minutes just to read the passage, but then if you read the passage correctly, it should set you up to only have to spend 0:45 - 1:00 answering each of the four questions -- which works out to the same 8-ish minutes total. Does that make sense? Plus, you'll find that a lot of the sentence correction questions won't take you a full 2 minutes, and you can use that extra time on reading comp. The biggest way to improve your reading comp speed is to change how you read the passages themselves. The key, as I explain in this "tip of the week," is to read for "big picture": www.dominatethegmat.com/2011/10/gmat-reading-comprehension-tip-of-the-week/. Hope this helps!

Hi, Brett! You are a magician! Your video about strategies is amazing! Especially I liked making up numbers and WIBNI! I read an article about WIBNI on your website and I think that this principle has a much wider application to life than just beating the GMAT :) I not really liked the example of eyeballing because to me PQ is a little bit less than a half of OR and I even measured it on my screen with a ruler to check myself, so on my screen PQ is 2cm and OR is 4,4 cm so by using this strategy I would more likely choose E as an answer, that's why I would chose some different example for the demonstration of this strategy. Just wanted to let you know, because I am very grateful for your videos and I like them a lot and would be glad if my advice would help you somehow to make them even better. :)

Great approach, Brett. Interesting enough, but for the Sample Question: Variables Strategy (10 min 02 sec) if X=2, Y=6, Jim=2 and Lois=4, the right answer is E and not A.

@dominatethegmat

5 жыл бұрын

Notice that with your numbers, answer choice A also works. Every once in a while, the variables you choose may result in two potential "right answers" (purely by coincidence). If that happens, simply work the problem again with a different set of variables and it will eliminate one of those answers, leaving the one true correct answer. If you follow my rules for making up numbers, this occurrence rarely happens.

I like the variables strategy, I'm not sure about WIBNI

Glad you've been finding them helpful! I know you'll find my full course even more so :) Do you mean that you're planning on taking the GMAT 11 months from now? If so, my advice would be not to drag the process out that long. Most people only need 2-3 months (~80-100 hours) to fully prepare for the GMAT from scratch. If you have the time to start studying for it now, then definitely do so. Track your practice test scores and make sure you're progressing as desired, but then go ahead and pull the trigger on taking the real thing as soon as you're ready -- possibly as early as September or October. Your score is good for 5 years, so you might as well get it out of the way! (In terms of other advice, balance your studying across the "Success Triad" principles I discussed in Part 1; my course will provide you with the ideal game plan, teach you all of the most important content and strategies, and give you tons of practice). Good luck!

Hi Brett! Thanks for the videos! Very helpful for myself and I am sure many others. I wish to apply to Ontario based business schools that do not mention on their websites that they consider the essay or integrated reasoning. Should I almost completely skip these sections to help prevent mental fatigue?

@dominatethegmat

10 жыл бұрын

I wouldn't advise "almost completely" skipping those sections, no. Whereas a lot of schools don't but much attention on the essay or IR, they do see it as a red flag if your essay and IR scores are disproportionately worse than your main GMAT score. I imagine that would apply to your Ontario schools. If you get a 650 on the main part of the GMAT but a 1 or 2 on the essay and IR sections, it could be a problem for you. Whereas you don't need to over-tax yourself and try to get a 6 or 8 respectively, I would suggest at least making some effort on those sections. Prepare for the extra "mental fatigue" when you take your practice tests and you should be fine.

Thank you for the videos, but no need to estimate on this one: Since the alternate interior angles are the same, the other arc on the top right is also 70 degrees. The bottom is a semi circle, so it is 180 degrees. Subtract 70 and 70 and 180 from 360 (a full circle) and you are left with 40 degrees. 40/360 is 1/9. The diameter of the full circle is pi times D, or 18pi. So 1/9 of 18pi is 2pi (sorry i don't have the pi symbol).

You're absolutely right about the mathematical solution, but the point with this video is that sometimes you may not know how to do the math, and you need a strategy to still get a right answer. If you know the math, go for it! But even if not, I still want you to be able to get right answers :) That's what dominating the GMAT is all about!

Helpful = Make up #s Opportunity for improvement = timing.

Do you have a course that I can take for Data Sufficiency questions in general, and not specific areas of math? My math is strong, and I don't have any problems with Problem Solving questions.

how did you do on the GMAT?

@dominate the GMAT - In the geometry problem how did u assume the length of the parallel line segment PQ is one third the length of the diameter. That is pure approximation. Also, even if we scale the figure and try to find the answer we are left with two very close options, which might leave us with doubt in the end. And the doubt would make us think if we did actually choose the correct approximation to begin with.

@dominatethegmat

10 жыл бұрын

Good point, Hardik, and that's exactly what I explain in the video. It is an approximation. The "eyeball technique" isn't a foolproof way to get THE one right answer (although sometimes it is), but it's a great way to eliminate some clearly wrong answers and improve your guessing odds in the event that you don't immediately know how to do the math. In terms of how I approximated the length of PQ, I used the fact that problem solving figures are assumed to be drawn to scale, and I encouraged you to literally hold a piece of paper up to your computer screen to use the diameter of 18 as a scale key. Again, it's not an exact science, but you can get pretty darn close.

There are so many comments and I tried going through the first few... but is there actually an explanation on the geometry question we were eyeballing? Trying to see if my thought process actually worked... Also, read up on WIBNI Blog... will do so again, to try and visualize it for myself as I am a visual learner. Your videos are great, thank you so much!!

@dominatethegmat

6 жыл бұрын

My pleasure, glad you found it helpful! I teach the actual geometry for the "eyeball" question in my course, but here's a quick explanation. The key is to recognize that an inscribed angle has 1/2 the degree measure of the arc it creates. And given the rules of parallel lines cut by a transverse, that means arcs OP and QR both measure 70 degrees, leaving 40 degrees for arc PQ. So the question becomes, what does 40 degrees translate to in terms of an actual length? Well since there are 360 degrees in a circle, that means arc PQ represents 1/9 of the circumference of the circle (40/360). The circumference of the circle is 18pi (we're told the diameter is 18, so the radius is 9), so the arc is 1/9 of 18pi, or 2pi.

2nd strategy is good but fails sometimes may b i am making some mistakes but overall i really liked these stategies. thank u

Glad to hear it! Yeah, it takes a little practice until these strategies become second-nature. Stick with it! And whenever you're ready to dive even deeper into the other content areas and strategies that will help you dominate the GMAT, you can sign up for one of our comprehensive courses here: www.dominatethegmat.com/video-purchase/. Let me know how else I can help!

Thank-you for the video, I really like it, but unfortunately I fall under category 3 and I know a lot of these strategy before even watching this video, What I am concerned about is the verbal part of gmat, I am really very weak in that, could you please upload some of the videos which help me in that...

Great strategies. However, I think that line was just under half of 18. I'd have to lean towards B on that one.

At least the strategy would have gotten you to a 50/50 guess in that case...better learn how to do the actual geometry, then! ;)

Good morning Sir! I've just known about your youtube channel and this is my first time here so thank you so much for the instructions! I have an allegedly quicker way to solve the geometric quiz, could you please verify this for me? Thanks in advance Given that 2 minor arcs of PO and QR have the same length = 7pi/2 (cuz angles PRO and QPR are both 35 degrees). so arc PQ = 1/2C - 7/2pi x 2 = 2pi so it is A

Thanks for joining the discussion! I'm glad you found my channel. And yes, that's a nice geometric approach to the problem. I certainly teach that in my comprehensive course as well, but the purpose here is to help students understand that there are ways to get right answers even if you don't immediately know the traditional "textbook" approach to solving a particular problem. But of course if you do, go for it!
