GMAT Ninja's 24-Hour Nonstop GMAT Crash Course for Ukraine

GMAT Ninja's Nonstop 24-Hour Crash Course for Ukraine

(Almost) Everything You Need for the GMAT

By now, hopefully you’ve heard about our March 2022 ultramarathon GMAT fundraiser for Ukrainian charities. Early in the war between Ukraine and Russia, we wanted to do our part to help the current wave of Ukrainian refugees. GMAT Club’s founder, bb, is from Kyiv. My grandparents were from Kharkiv and Crimea, and they came to the United States as refugees after WWII. So the human toll of this war felt personal to us.

We decided to do a nonstop, 24-hour GMAT “crash course” as a fundraiser for five charities working in Ukraine. We raised $45,000, easily topping our original goal of $24,000.

The crash course itself was designed to cover everything you REALLY need for the GMAT -– albeit not in mind-numbing detail -– in a nonstop series of 24 one-hour lessons. I taught live on YouTube all night, and there was plenty of slurring, drooling, and fumbling. But hopefully, some of the content is legitimately useful if you're trying to conquer the GMAT. If not, maybe you'll at least be entertained by the slurring, drooling, and fumbling.

Want to learn everything you can from the crash course? Please keep reading.

A crash course for all skill levels: what you're REALLY doing wrong on the GMAT

The 24 lessons are all built around the same theme: instead of covering the basics of every topic, we focused on pitfalls that are common for GMAT test-takers across a range of skill levels.

The crash course also included a countdown of the 10 biggest study mistakes I've seen students make in my 20+ years as a GMAT tutor, along with interviews with experts who can help you overcome test anxiety and perform your best on test day.

See below for a full list of ALL of the questions in each hour of the crash course, as well as links to the videos for each of the 24 lessons.

If you find the crash course helpful, please donate to... something!

The 24-hour fundraiser supported the following charities that focused on helping Ukrainian refugees:

• Caritas https://www.caritas.org/
  
• Come Back Alive https://savelife.in.ua/en/
  
• International Red Cross https://www.icrc.org/en/donate/ukraine
  
• World Central Kitchen https://wck.org/
  
• Save the Children https://www.savethechildren.org/

If you’re passionate about supporting Ukraine, great: we’d love for you to support one of our chosen charities. If not, that’s wonderful, too -- instead, please find a cause that you care about somewhere in the world.

If you watch the lessons and think, “man, I would totally pay for this GMAT course!”, then please donate whatever you think the course is worth. Or if you think, "man, this guy is pathetic", please donate anyway, either to help people somewhere in the world or to help the pathetic guy feel better.

Again, if we've inspired you to donate a piece of your test-prep budget to a good cause, please let us know about it -- regardless of the cause.

Thank you to everybody who supported the fundraiser!

Full disclosure: bb and I concocted the idea for this fundraiser just eight days before actually doing it. And we needed a TON of help to make it happen.

I'm worried that I'm going to leave some amazing people off this list, but I want to thank a bunch of our friends who helped us :

• Huge thanks to our sponsors: Applicant Lab, e-GMAT, Stratus Admissions, MBA Mission, Personal MBA Coach, Admissionado, Stacy Blackman Consulting, and Gatehouse Admissions. I know that many of you didn't donate for the publicity, and that makes us love you even more.
• A special thanks to Cars Helping Charities, a wonderful organization that has nothing to do with the GMAT or MBA Admissions. This organization -- which is also dedicated to helping charities -- offered to sponsor the event not because it would raise their profile, but just because the organization is run by one of my former GMAT students, and he wanted to support the fundraiser. I can't possibly repay the love fully, but if you're reading this, please visit their website, and pass it along to anybody who might be able to link them with a charity who needs a hand with fundraising.
• It's a huge task to produce 24 hours of GMAT content, and I had a ton of help from heroic friends here at GMAT Club, several of whom stayed up all night with me. Evan, Selbi, Gauri, Doug, Kirsti, Souvik, Nikhil, and especially Abhijit, Bunuel, and Bogdan -- thank you for preventing me from making TOO much of an ass of myself. Thanks also to Dave, Dana, Bransen, Mike, Harry, and Alex -- six tutors who are frankly more talented than I am -- for shoveling questions at me, with minimal guidance. And huge props to Harry for giving me a breather in hour #19, and doing a better job with overlapping sets than I could have.
• I can't possibly list all of the people who put a smile on my face with their kind words during the livestream, but I wanted to give a special shout-out to anybody who survived for all 24 hours (Vubar and Dub C jump to mind, but I'm sure there were others); every viewer who asked for my hand in marriage; my lovely friends at Aringo, GMAT Club, Applicant Lab for sending food and caffeine; AndrewN & IanStewart for being wonderful human beings and amazing teachers; and my lovely wife Amber, who was on solo parent duty for 24 hours but still managed to find time to toss Red Bull, smoothies, espresso, and burritos into my office.

Thank you, everybody. It's a vulnerable feeling to babble into a camera for 24 hours straight while asking people to donate money, and every donation and friendly message meant the world to me.

FAQ about the 24-hour nonstop crash-course for Ukraine

Q: Did you really teach GMAT on livestream for 24 hours straight? With no breaks?

A: Yup. Please donate.

Q: Dude, weren't you a total mess?

A: Yup. Please donate, even if it's just out of pity.

Q: I heard that the Cooking Channel once called you a “legend of global gluttony.” So, like, how did you eat if you didn't take any breaks?

A: During most of the lessons, we put questions on the screen and gave viewers a few minutes to work through each of them; during the quant lessons, we'd sometimes offer a 10-minute, 5-question quiz. That time spent off-camera gave me enough time to shove food in my mouth. Lots of food. And three or four smoothies.

Q: Did you drink enough caffeine to, like, choke a moose or something?

A: I drank less than I expected: a double espresso, a half-pot of coffee, and a Red Bull.

Despite what the ads say, Red Bull didn't actually give me wings, but it did make a vein in my forehead twitch uncontrollably during hour #21.

Q: Um, what did you do about pee breaks?

A: I borrowed my son’s diapers.

Q: Eeeeeewwwww. You’re gross.

A: Yes, I’m gross. And I’m joking about the diapers –- they don't fit, since I'm a legend of global gluttony. Don't worry, I used a nearby toilet as needed when questions were on the screen.

Q: Weren't you worried about having a stroke or something during the marathon?

A: I wasn't worried. I’m pretty sure that Bunuel would have been able to heal me via the internet if anything had gone wrong. After all, the Holy Grail and Bigfoot are both looking for him.

Q: How did you teach 24 consecutive lessons without making epic mistakes?!?

A: I made epic mistakes! Check it out, it was pretty fun.

Q: Where can I find the videos?

A: The 1st 12 hours are here and the 2nd 12 hours are here. I will be very embarrassed by them someday (like, um... today), and so will my children.

Q: Why are there separate links for Part 1 and a Part 2? Are you trying to pull something here, you slimy ninja guy?

A: YouTube only allows us to livestream for 12 hours at a time. If we go past that length, the video will get deleted. So we did a livestream for 12 hours, switched to a new link, and then continued for another 12 hours. Because we did it in two chunks, you can watch the videos anytime, and I'll be able to embarrass my children forever.

Q: How did you choose the charities for the fundraiser?

A: We chose highly-rated charities that have the infrastructure to help immediately in a war zone. In most cases, we've spoken with contacts at the selected charities, and we're confident that they do good work and use donations wisely.

If you donate to the GMAT Club fund, we'll spread the donations equally across the five charities. You're also more than welcome to donate directly to one of them -- just let us know, so we can count your donation in our campaign totals.

Q: Can I still donate?

A: Yes! We'll keep the list of charities on this thread as long as Ukrainian refugees still need their help. If you found the crash course helpful, please donate whatever you would have spent on a prep course of similar quality.

And if you'd prefer to donate to a different cause in a different part of the world, that's wonderful, too.

_________________

Aside from the fact that this is going to be EPIC. More EPIC than Manowar themselves

The other thing you nailed in the above post (scheduling apart which is insane) is the fact: Is X true? YES please donate. Is Y true ? YES donate................

Guys, folks support Ukraine in this out-of-this-world, inconceivable, unbelievable terrible moment. Support the community in this herculean effort!!!

Regards
Carcass

Thank you so much Charles for doing this event - this is amazing. I hope you/us/people in Ukraine (and other unsafe parts of the world/everyone survives. This is an amazing fit of self-sacrifice with great usefulness
I love the Q&A - definitely a good distraction! I am more interested in the food and GMAT-score-enhancing foods
_________________

I hope they keep the recording in youtube with all the links to donate so that even if people miss the deadlines, they can donate post watching the video whenever they do

Great effort that the team is determined to put forth to help Ukraine.
I can't even imagine what Ukrainians must be going through. As a Civilian doing something that is so different and something we have never thought in wildest dream. My heart goes out to all the people.

GMATNinja bb This is a great effort by whole GMATClub team benefitting everyone with a session for charity.

I have few questions:

1. Sadly, we all are not as super as Charles to attend 24 hours session. So, will it be there on YT for future references?

2. I see few Quant topics are TBD. Can there be one topic for Nasty word problem. Word Problem that looks like passage, and how to break it systematically?

3. In the other thread I saw educators ready to contribute - Can we have a Quant session Ian and Chetan (If they are Ready). It will be great if even Harry from GMATNinja takes a session.

4. A topic on Mock. How to take, When to take and what to do when 6 Official mock are not enough. How to prepare your own Mock set. - I have seen this discussed. But if you have a slot to discuss this.

I have donated and also ask others to donate for Humanity and all the efforts that the team puts up.
We have 3 more days to go (Depends on your time zone)

bb GMATNinja
Could you please tell us whether 24-hour nonstop crash-course for Ukraine will be available on the GMAT club youtube channel once the live session is finished?

Some people might not be in the whole session for work and other obligations.

Thanks!

Thank you for this question, everybody! Yes, the marathon will be available on YouTube afterwards. We're still working out the details, but in all likelihood, we'll leave the full, unedited video up on YouTube, and then we'll also break them into one-hour chunks by topic and repost those, too. At least the ones that don't involve too much stumbling and slurring.

So don't worry: get some sleep, and you can watch anything you missed later. But feel free to keep the livestream going on your computer while you sleep, just so that I think you're there.

Friends, just a quick note to say that I've updated the schedule in the top post above.

It's very possible that we'll make last-minute changes during the livestream if something weird happens, but this is pretty much the final schedule. If you have specific questions or requests about these topics, just let us know!

You mastered the light side of the force on Tatooine.

You could last well beyond 24 hours.

Will be fine. Your effort is for the right cause: the students who believe in you. Also for the amazing fund-raising for an utterly mad scenario that someone could avoid.............

Keep your own pace.

Will be fine.

Charles -

I wanted to thank you personally for putting yourself through so much to help others, both the members of GMAT Club who watched your lessons with great interest and the unseen beneficiaries of the larger donation drive. I will confess that this was my first time watching any of your content. I simply prefer to read instructions or teachings, to be able to skip around according to my own understanding of the content. But from the moment you started the marathon, I was engaged. (I was watching while running, sort of participating in a challenge of my own creation: run without soled shoes for 20K, all while breathing through my nostrils only. My efforts were buoyed by your own, and I made it.) I watched hour after hour, in disbelief that another hour had passed in the middle of every hour on the clock. I even participated in the chat from time to time, as you noted yourself at some point when Ian Stewart and I had an exchange.

From the perspective of a tutor, I can say that I felt validated in many of my own pedagogical techniques when I saw you offering similar advice: I use "housekeeping" for "hygiene," for instance, but the idea is the same, and I also eschew mechanical thinking (although sometimes to a fault in Quant). I got up before 4.00 the next morning because I knew you would still be going, and I stayed with you until I had mere minutes before my first meeting of the day with a client. But that last hour was a treat. No, I do not enjoy watching others suffer, but you seemed to be having so much fun, working through those difficult Quant questions. I think I recognized every one, and I missed the same inequality question some time back for the same reason—I made an assumption. At least you had a legitimate excuse.

I left that marathon lesson feeling inspired, wanting to improve certain aspects of my tutoring, getting back to basics in my practice sets of questions. To be honest, I was in a lull with Quant after hitting a high in December. (I even wrote a post about that triumphant moment when everything had seemed to make sense.) But seeing that you were employing sound logic to work through those difficult questions, even at the end of your tour of duty, I decided to go back to those same GMAT Club Quant questions, new ones, with a different mindset. I stopped thinking about outcomes and just worked from the ground up. So far, I have not missed a single question, even one of those 95-percent-difficulty questions in a set from earlier today. Sometimes I like to say that when I teach, it is as though I have waved a magic wand, and my student is enchanted with pixie dust for a while, feeling as though nothing on the test was insurmountable. I have seen such a marked change in my students before, as I am sure you have in yours. It was a rare opportunity to be on the receiving end, but all I had to do was watch and listen. You are a professional and an expert among peers.

Thank you for being so generous.

- Andrew

I have been going over these throughout the weekend, what an amazing series, thanks Charles GMATNinja ... the real treat was to see your parenting skills on 10:38:28 .... so cute!! Love this series ... trying to watch my back! Cheers!

Aw, thank you so much for the kind words, IN2MBB2PE! I'm glad that the marathon is actually useful for somebody. It's all such a blur now, and I'm not convinced that I said anything coherent, especially once we got past hour #3 or so. Maybe I'll watch some of the videos for Halloween next year, since the footage probably resembles a zombie movie.
