Thank you! Also not sure why my quant suddenly got worse, especially in algebra over the last few weeks. My initial mocks used to be around 81-85 on the official mocks but after taking my first attempt and getting a score of 71, on the GMAT sectional mocks I’ve been scoring 79, 80, 81

Gotcha, why do the test quality degrade if there are no repeats?

Because it has fewer questions. Imagine someone who is scoring 555 someone who scoring 665 and someone who scoring 775 taking a test that’s lacking a diversity of questions. That means one of these three individuals is going to get either a lot of hard questions or a lot of easy questions that they really should not be seeing and that are really not representative of their level because the question bank only has a more limited question bank, the quality of the score prediction is going to be lower meaning the standard error is going to be higher

If you’re referring to the GMAT Club test, they are a bit tougher and questions tend to be more thought-provoking than the more standard template driven ones in GMAT prep. What I’ve heard from a few people is that your final GMAT score will be somewhere between your gym prep and your GMAT Club quant test. But use common sense and dive into the mistakes and focus on them as a source of improvement. It’s good to get beat up now rather than on the test day 😂

Following these lower scores, I’ve been reviewing the questions and for the most part it’s been silly mistakes with a few outliers being concept related

You can use three and four. There’s no big deal. And I would save at least one test with two attempts just in case you need to retake. The benefit of taking one more official test is not big but not having any official tests when you need to retake is a huge pain point

And I would love to know your official score when you take it in three weeks so I would really love and appreciate the debrief.

PS. We are working on the new scoring algorithm that uses the same methodology as the official GMAT and we have the prototype already but it’s not calibrated yet and I’m not sure if it will be done in time for your test but if it is, I’ll be happy to share it as it’s supposed to have the most precise scoring... 😇

Since I have three weeks till my second attempt, would this be fine -> 1st week, Mock 3 retake, 2nd week - Mock 4 retake, 3rd week either Mock 5 or 6 (save one for future just incase) and then use sectionals for quant / DI to help prep throughout?

Of course! I’ll keep you updated :) My first attempt was 645 (Q78, V86, and DI82)

Guess my goal for the second attempt is 695+, by ideally maintaining Verbal, and increasing my Q78 to Q85

Yep. Sounds like a good plan. Make sure you dedicate enough time to every mistake so it’s not 90% of the time spent on taking tests and only 10% spent on learning and studying.

You build your score by learning material and learning strategies and learning traps. Taking a full test is more like a test of you being able to apply that learning so if you over index on taking tests, you get really good at applying but then you don’t have enough learning to be applying so to speak 😇

Since you are retaking, I think you’re more experienced than these things so I’ll drop the basics

Back at the time of dinosaurs when I took my gym at, we only had two free official tests and zero paid ones. You could retake the official ones a few times which we all did but there was a lot of fewer tests available and we’re still managed to survive so well today the benefit of many tests is great, the learning part is still important

The hardest part about studying after making mistakes is that I feel like the mistakes I’ve made are so careless and stupid. And for the concept related mistakes, it’s mainly because I couldn’t spot the hidden pattern rather than know what to do after seeing the pattern.

Should I just continue to maintain my error log + try my best to find these patterns? I’m noticing nearly 60-70% of the questions I’ve been getting wrong are algebra based because I was overwhelmed by the equation given or unable to spot the pattern and feeling rushed due to the time factor

At this stage, only three weeks before the test, you should really sit back and think about how you could eliminate careless mistakes. Maybe not all of them but at least some of them because that’s what’s going to be the main difference between a high score and the low score. It is possible to eliminate them so don’t approach the issue as though it’s an impossible task. For example, I would spend five seconds between my quant questions resetting my brain because if I didn’t do that, I would make some careless mistakes. I also read the questions twice on the quant and I also did a quick check at the end to make sure that the answer I came up with made sense and I didn’t fall for any of the usual traps.... There are things you can do but they will require effort and time potential test time. But I would encourage you to think about every single careless mistake and consider ways of eliminating it and think creatively

I feel like at this point in time you have enough mistakes. If you have not been identify the patterns until now, doing another few hundred questions is not going to get you there so start treating every single mistake like a VIP. You don’t have patterns with VIPs you treat each one of them in a very special way. So every time you make a mistake you go when you do a triage and figure out why and what went wrong and how can you not make this same mistake again. Because if you make some mistakes over and over, there’s no point in continuing it’s like trying to get water out of a boat that has a hole. Do you have to plug the hole before you start taking the water out of the boat 😂

Critical Reasoning Butler: January 2025
January 2CR 1CR 2

____________________________
CR 1

The Sekhon class jet turbine, composed of a new and improved steel alloy, will cost more than thrice as much as the current model of jet turbines does. However, replacing older turbines with newer models should still reduce costs. Not only will installation time be reduced, but the Sekhon class turbines should last longer.

Which of the following must be studied in order to evaluate the argument presented above?

A. How likely is the use of the Sekhon class jet turbine to reduce the need for future repairs, in comparison with the use of the current model of jet engines
B. How much the cost of producing the current model of jet turbines has dropped, following the advent of the Sekhon class jet turbine
C. How long it takes to install a new jet turbine versus how long it takes for the jet to be cleared for flight
D. How much more care is taken in the manufacture of the Sekhon class jet turbines produced with the new alloy than in the manufacture of the current jet turbines.
E. How much more affordable jet turbines produced with the new alloy will become as the production procedures standardize and become applicable on a larger scale.

____________________________
CR 2

Alpha Deliveries has recently switched at least partly from older packaging using rigid materials to new packaging made from flexible plastics. The question has been raised whether it can be concluded that for a given level of output Alpha’s operations now cause fewer resources to be consumed than it did formerly. The answer is yes since the amount of raw material, energy, and manpower needed to produce and use the flexible plastic packing material is less than that needed to produce and use rigid packing material, provided the level of output is held constant.

In the argument given, the two boldfaced portions play which of the following roles?

(A) The first identifies the content of the argument’s conclusion; the second provides support for that conclusion.
(B) The first expresses the argument’s conclusion; the second questions that conclusion.
(C) The first provides support for the argument’s conclusion; the second identifies the content of that conclusion.
(D) The first provides support for the argument’s conclusion; the second questions that conclusion.
(E) Each provides support for the argument’s conclusion.
