GMAT Ninja Quant Ep 0: How to Approach GMAT Quant

[@ariyanakhan1816]

I took my exam today after close to a year of prep (9 months of actual serious prep). From a 425 on my cold mock earlier this year to a 645 on my actual exam today, it's been a rollercoaster ride (quite literally but that's a story for another day). GMAT Ninja's videos have been a lifesaver in my GMAT prep. Although my score is a tad bit far from my target score, I am extremely grateful for these resources. THANK YOU!!

Was it GMAT Focus?

[@aishwaryapophali2017]

never in my life i have liked math, you made me realise i just needed to change my approach, fabulous work creating these videos!!

[@GMATNinjaTutoring]

This is the best comment ever. Thank you so much for the kind words! And seriously -- this stuff can be kind of fun if you give yourself some space to enjoy it. Not that testing is the funnest thing ever, but if you think of the quant section as a bunch of games or puzzles -- built on a foundation of high school math -- you can have some enjoyable moments with it. :) Have fun studying, and please keep us posted on your progress!

[@amshuhasm2441]

Thanks a ton Charles! This and every other video from GMAT Ninja out there is absolute gold. You guys really get to the heart of what GMAT is all about. I'm always recommending GMAT Ninja content to literally every Gmat aspirant I meet. Love the way you guys teach. True legends. Finished my exam a few days back, scored a 705. Couldn't have done it without you guys❤️

[@GMATNinjaTutoring]

Holy smokes, congratulations on the 705! That's an epic score on this version of the test. And thank you so much for the kind words. I'm honored that we could help a bit. Good luck with your applications, and please let us know where you land for grad school! - Charles

hey bro how many mocks did you give ?

[@amshuhasm2441]

[@bhavanadandu7879]

Binge watched Charle’s videos to the extent that I instantly remembered his crystal clear explanation to the 3rd question in his previous videos from months ago! -officially a Charles fan, thanks for all the work!

[@GMATNinjaTutoring]

Haha, thank you so much! Fwiw, you'll see plenty of recycled questions in the quant videos that we're publishing in the upcoming weeks and months. We're mostly just updating the messaging to reflect the new score scale (and the small handful of other things that have changed on quant). Many of the questions will be the same in both the old videos and the new ones. Hopefully my explanations haven't gotten too much worse over the years! ;)

[@ManenChowdhry]

I just can't thank you guys (especially Charles) enough. You are so thorough in your teaching and it has been very much helpful. I felt kind of lost, on where and how to start and continue, before watching your videos. Now, I am getting to know how to approach each and every aspect of GMAT prep.

[@VidurSeth-b7o]

Thank you for these, you're a life saver. Best content out there to whoever is trying to study for GMAT themselves. Very practical, very intuitive and perhaps the best teaching style I've come across. Thank you so much!

[@GMATNinjaTutoring]

Thank you so much, and have fun studying! ❤️

[@noahmiller1980]

Your channel is unbelievably good! I'm having fun learning. Thank you so much. Will report back with my score if/when I take the GMAT!

[@vijaysacademy]

Last question explanation was brilliant. Instead of doing lot of math we can answer it easily with some logical thinking

[@GMATNinjaTutoring]

Thank you so much, Vijay! You'll see quite a bit of that on the GMAT -- sometimes questions look like math, but sometimes most of the math itself is very, very avoidable. Have fun studying, and thank you again for the kind words!

[@manisharaste4918]

Can you explain the last question?

[@nadakurdi1435]

This is the best video on youtube

[@GMATNinjaTutoring]

Aw, thank you so much! Personally, I prefer the videos of fainting goats, but that's just me. 😃 Thank you again, and have fun studying! - Charles

[@alexfung6312]

for the problem at 22:13, why can you not use b =3/5(c+d) to solve for b, then plug this value into the original equations to solve for c?

[@GMATNinjaTutoring]

You're aiming in the right direction, but you've made an error somewhere in your algebra. As Charles shows in the video, we can generate the equation c = 3/5(b + d) from the information contained in statement 2. There's no way of rearranging this to give b = 3/5(c + d), but we could rearrange it to give b + d = (5/3)*c. We can then substitute this into c + (b + d) = 360 to give c + (5/3)*c = 360 and solve for c to answer the question. I hope that helps!

[@MauricioAcuñaCaro]

Here after taking the gmat and having achieved my desired score mostly thanks to your very comprehensive series. Thank you Charles!

[@GMATNinjaTutoring]

Thank you so much for the kind words, Mauricio -- I'm honored that we could help a bit. Congratulations, and good luck with your applications!

[@gowriuh09]

Thank you so much for all your classes I'm thinking of taking the GMAT for second time. So please help.

[@amanuttam7222]

Hey Charles! Thank you for all the content you and the rest of the kind folks at GMAT Ninja put out there for us! It is really appreciated :) Just wanted to know- that once we are through with these videos- im always left wondering on what i need to do to really 'cement' the topics covered in a video. For example If im done watching arithmetic, and i pick up a lot of practice questions from GMAT club- how do i know when I'm done with that topic. The number of practice questions are endless- would you recommend just going through the OG alongside these videos as well and then diving into mocks? Would love to know your insights on the resources. Thanks again!

[@madk5864]

Highly recommend these videos!

[@ratand4619]

Charles is the best. Really excited for these new vids on quant topics. Especially the teaching style of charles is so amazing that i might not get everything at once, but sure as hell always gets be excited to study it. I just have one question, im 20 just graduated from liberal arts background, for me verbal isn't a burden, for me its quant and DI, although im always genuinly excited to learn the topics from root level, i sometimes dont understand the question and fail to frame the question so i can get everything straight? What do i do?

[@GourabNath]

great explanation sir. very very thank u for this classes. the playlist is very helpful for me.

[@GMATNinjaTutoring]

Thank you so much for watching, and have fun studying!

[@OpenCSE]

Will the whole Quant playlist be updated with new videos?

[@sindisosikosana3196]

Hi Charles, how did you pre-solve the percentile injuncture considering the values do not resemble interchangeable values nor integers.

[@TheSchmukk]

Hey Charlie, you suggested that we shouldn't be afraid to "skip" a question so we continue to stay on track time wise. What happens if the question is early on, and considered "easy"? Does that mean the rest of our test is basically done, since you gave the study results of how a 90th percentile scorer who misses 2 qns early on loses 80 points?

[@GMATNinjaTutoring]

Thank you so much! ❤️

[@TheSchmukk]

@@GMATNinjaTutoringu didn’t respond to the question tho

[@victoriacavalieri4950]

Hi Charles! What would you recommend for someone that got an 645 and wants to get to 675 in about 3 weeks? I only got 3 questions wrong in quant but but score was in the mid 70th percentile due to careless errors I think :/

[@Dhruvaverma24]

Hey Charles! Are these practice problems directly linked to the actual test?

[@GMATNinjaTutoring]

We write the questions that you see in our quant videos, but they're written based on our familiarity with every retired GMAT test question that's been released in the past 25 years. So you won't see these exact questions on the exam, obviously -- current test questions are never made public. But the questions you see in our videos are generally good representations of the types of things you'll see on the actual exam. I hope that helps a bit!

[@harispolydorou9726]

but the questions are gonna be on the computer screen, how will i be able to for example do some "calculations" on the answers like you did in the final question of the video. Surely it wont be worth the time writing down the questions

[@emilygoggin8609]

Thank you soooo much, this was super helpful

[@GMATNinjaTutoring]

Thank you so much for watching! ❤️

[@JohnWick-n7o]

when will the full update of quant playlist be finished?

[@ryanniederreither5238]

On Q2: I really don't understand why 2 alone is sufficient. How does c+5/3c =360 give you what you need? To me, that equation makes no sense. Do I need to brush over the fundamentals?

[@GMATNinjaTutoring]

In this question, we're trying to work out whether the information provided is sufficient for us to know how much Chuck spent on cookies last week. Essentially, we want to find a single numerical value for c. If we know c + 5/3 c = 360, then we have an equation with a single variable that we can solve to find c. At this point, we can say the information in statement 2 is sufficient to answer this question. We could go further and solve this equation to prove the information in statement 2 is sufficient. If we know c + 5/3 c = 360, we can sum the terms on the left to give 8/3 c = 360 or c = 360 * 3/8 = 135. We now know for sure that we can find the amount of money Chuck spent on cookies last week from the information in statement 2 because we know the figure is $135. I hope that helps!

[@varunalla]

Are we getting a Updated Verbal Course too?

[@GMATNinjaTutoring]

Absolutely nothing has changed on GMAT Reading Comprehension or Critical Reasoning, so we don't have any plans to update those videos. Everything we teach in our CR and RC videos applies equally to the new and old versions of the GMAT. I'm sure that we'll get restless enough to make changes to those videos at some point, even though the questions themselves haven't changed. But at the moment, we have no plans to do so. Have fun studying, and thank you for watching!

[@640dm]

quick question how do we know which are the hard questions?

[@GMATNinjaTutoring]

Good question. You definitely don't want to waste any brainpower trying to figure out what the GMAT considers to be difficult -- that's not productive. Instead, just think of it this way: if a question is easy for you, then you need to be 100% systematic so that you don't make a careless error on it. If you don't see a reasonable path forward within the first 30-60 seconds, then you can consider it hard, and you won't want to waste time on it. I hope that helps a bit!

[@yadnyeshmandlik2213]

Can we use focus edition 23-24 books for exams in 24-25??

[@GMATNinjaTutoring]

Yes, that's fine. Some additional practice questions were added for the 2024-25 edition, but I don't think they're game-changing. The only potential exception is that there are a few more "non-math-based" Data Sufficiency questions in the 2024-25 editions -- but I don't think that's a reason to buy entirely new books. I hope that helps a bit, and have fun studying!

[@samarjeet6803]

Sir is this syallbus are according to gmat focus edition or normal gmat please sir reply ❤ Love from India 🇮🇳

[@GMATNinjaTutoring]

The GMAT quant syllabus hasn't changed much at all from the "old" (pre-2024) version of the GMAT to the new one (formerly called GMAT Focus, now just called "GMAT") -- geometry was removed, and data sufficiency migrated over to a different section. But other than that, the math domain itself is exactly the same. This particular video was filmed in 2024 with the "new" GMAT in mind. Some of the videos on our quant course playlist were filmed before the change in format, and they might use some outdated language, such as references to the old score scales -- but if you see a video on our playlist, the content is still 100% relevant for the current version of the exam. I hope that helps a bit, and have fun studying!

[@swethareddy7460]

Hi, i couldn’t get how 1/root 2 is greater than 1/2, could you please explain

[@GMATNinjaTutoring]

If two fractions have the same numerator, the one with the smaller denominator will be larger. For example, 1/2 is greater than 1/10, and 1/100 is greater than 1/500. Using this, we can say that since sqrt(2) is smaller than 2, 1/sqrt(2) will be greater than 1/2. I hope that helps!

[@lordgrimm1974]

I'm I the only one thinking of using Venn diagram for the question

[@harshitarora9044]

Read twice even for long questions? Some questions can get quite lengthy.

[@GMATNinjaTutoring]

Yup. It might even be MORE important on those longer quant questions -- if you misread the question and just start doing stuff, there's a very good chance that you'll waste even more time on processes that are inefficient or just plain wrong. And of course, if you miss a question that's not difficult for you -- regardless of its word count -- that's absolutely catastrophic on an adaptive test like the GMAT. Think of it as an investment: spend a bit more time up front to save yourself far more time and pain later. I hope that helps a bit!
