On the new GMAT Integrated Reasoning section, there are four major new question formats:

Watch this video (below) to learn the best strategy for attacking two-part analysis on the GMAT Integrated Reasoning section, as well as to see a step-by-step explanation of a typical two-part analysis question like what you can expect to see on test day.

A little bit about two-part analysis. Two-part analysis questions are going to present you

with a brief written scenario, again, integrating verbal with quantitative, so you’re going

to have a written scenario that’s going to ask you to make two choices related to that

information. And so you see here a picture of what these two-part analysis questions

are going to look like. You’re going to have Column A that you have to fill in and Column

B that you have to fill in. And those are your two choices, and they are going to be

connected in some way. And you’re going to see what I mean when we look at a sample here

in a moment. And really, it’s similar to the rest of the GMAT. In other words, the types

of questions you’re asked, the prompt you’re given is going to be very similar to everything

else you’re already preparing for on the GMAT Quantitative and the GMAT Verbal section.

We’ll actually come back to this hypothetical example in a moment, but here is what I mean

by that. Some features of two-part analysis, first and foremost, the question type that

you just saw, this is the first time you’re seeing it, and it’s called two-part questions.

1:02

And you’re going to have four of them. And just as we saw, they are questions where your

answer choices are all listed here, and you’re picking one of those answer choices for Column

A and one of those answer choices for Column B. And Column A and Column B will be described

in that question prompt. So again, your possible answer choices are given on the right side,

in that third column, and your choices, the choices you have to make, one for each column,

are listed there in those first two columns. Again, not something you have to memorize,

but just introducing it to you here and you’re going to see an example here in a moment.

Again, an average of 2.5 minutes for each of your Integrated Reasoning questions because

there are going to be four two-part analysis questions. You could expect to spend about

10 minutes total on two-part analysis. Now the general strategies start to look familiar

to you. It’s the same general strategy as for the other three question formats. You

2:01

want to start by understanding the prompt, planning your approach, and solving the question.

Let’s take a look at the specific strategy however for two-part analysis. And the specific

strategy is this: you’re going to be starting with that prompt and you actually want to

read that prompt first. You want to read the given information and try to figure out what

they are asking, what type of question is it — is it critical reasoning? Is it statistics?

Is it probability? — so that you know how to plan and prepare. You don’t want to rely

on prior knowledge. Everything that you’re going to need to answer the question is going

to be contained in the information in your question prompt. Then you want to determine

what the question is asking. Again, what are those two columns all about? Are they connected

in some way? And before you start to choose the best answer for each column, you want

to review all of the answer choices. You want to do that before choosing an answer. Are

the tasks dependent or independent? And remember, I’ve seen students do this where you’ll actually

3:00

accidentally pick a couple from each column. You only are making two total choices only

one from each column. And of course, both actually have to be correct to get the total

question correct. There is no partial credit, as we’ve seen on integrated reasoning. So

what’s tested? Well, quantitative is fair game. Verbal is fair game. If you see a question

that’s quantitative in nature, really, it’s open season. Honestly, they can ask you about

anything and everything that you’re already having to prepare for for the quantitative

section of the GMAT. It could be algebra. It could be statistics. It could be probability,

combinatorics, word problems. I mean everything that you’re studying already is open season,

and that’s good news for you. The good news is, like I’ve said before, there is nothing

new to learn, and yet on the other hand, quite a bit that you can be asked, so anything and

everything there. Now in terms of the verbal section, it’s mostly going to be critical

reasoning. And I say it’s critical reasoning in disguise, and what I mean by that is it’s

very vaguely disguised. You’re going to be asked to strengthen or weaken arguments. They’re

4:02

going to ask maybe to identify assumptions. It could be some cause and effect things.

And there may be little logic games. And in fact, we’re going to look at a second example

here where I introduce that. That’s the only thing that might be a little bit new and it’s

not rocket science. It’s not overly difficult but it’s just a new way of thinking about

verbal word problems. So here we have a sample question. And I want you to press Pause. I

want you to look at it. You actually have already been given your question, so think

through that. Read that. Do everything I just talked about in terms of the specific strategy.

Get your mind around everything that’s being asked, and then we’ll work this together.

Go ahead and see if you can answer the question on your own. Go ahead and press Pause. [Pause]

All right. How did you do? Well, it’s a combinatorics question, right? I mean this is straight up

quantitative section. You need to identify the number of possible combinations for each

of the beds, and that’s obviously what Column A is and Column B. Column A, it’s almost like

5:02

you’re answering two questions in one. If this were the quantitative section, you probably

only would have had to figure out, for example, how many combinations there are for the different

types of flower arrangements in Bed A, for example. Here, you have to do both. How annoying.

But they give you more time to do it, so good for them. Now you should know how to do this

go back and review that. But we’ll take a look at how to actually do this math, and

they give you all sorts of different information up here. So let’s take them in turn. And here

is how you’d want to use your scratch paper. So Step 1 is let’s just do Bed A. Let’s just

do one column at a time. How many combinations are there for Bed A? Well, how many total

types of flowers are we told that there are? Well, first things first, they tell us that

there are six different types of annuals, right? We have four different types of perennials,

5:57

and we have seven types of shrubs. So this is just kind of my cheat sheet just to remind

myself of exactly what I’m dealing with. Now, we’re being restricted in a certain way, aren’t

we? For Bed A, what does it tell us? Bed A must have exactly one type of shrub, so Bed

this out just like I have horses finishing in a race or whatever. At the end of the day,

how many flowers am I putting here or shrubs or whatever? Five. It says it contains five

types of shrubs or flowers or whatever. So I’m going to divide this up into five different

slots because that’s what I have to figure out what’s going on, right? And so I have

Slot 1. Now it’s telling me that Bed A must have exactly one type of shrub, so how many

shrubs could possibly go into this bed? Seven total possible choices, right? So seven possible

shrubs could go here. Now, filling the next spot, we’ve already used up our shrub, and

7:02

then it has exactly two types of annuals, exactly. Notice “exactly.” It’s not going

to have more than two. And also, we’ve also used up our shrubs, so the shrubs are done.

In terms of the annuals, we have an annual here and an annual here. Now how many annuals

can we choose from? Well, we can choose from among six annuals, so six possible annuals

can go here. And then once we’ve placed that first annual, how many could go here? Well,

there are only five left, so five possible annuals can go there. Now, here is the catch.

Is this a permutation or a combination? In other words, this could be Annual 1 and this

could be Annual 2, or this could be Annual 2 and this could be Annual 1. We have to account

for the fact that we have exactly two but not both combinations, so we have to factor

out the overlap. We have to divide by two factorial (2!). Does that make sense? And

if not, revisit the combinatorics lesson where I explain this in more detail. But you should

8:00

recognize that that’s the case. And then the final two spots, of course, then must be perennials

because we’ve already placed our shrub. We’ve already placed two annuals, and now we have

two perennials left. How many total perennials could possibly go in this spot? Four. And

then once we have placed those four, or the one, how many could possibly go here? Well,

there are only three left to choose from, so three could go there. But just as we saw

with the annuals, we need to factor out the overlaps, so we have to get rid of the two

factorial (2!) overlap because it’s a combination, not a permutation, and that’s your math. And

remember, we multiply all of this together. So it’s 7 times 6 times 5 over two factorial

(2!) times 4 times 3 over two factorial (2!). And the good news is you have your calculator.

And when you do all that out on a calculator, what do you get? 630. So obviously, you’re

going to have to trust me here or get out your own calculator and do it. And you should

be able to figure out how to make that math equal 630. And one you do and you look over

9:02

here, there you go, we’re halfway home, right? Because Bed A, we choose the correct answer

choice for Column A, which would be 630, so we’ll bubble in that one right there. That’s

it. And now we simply do the same thing for Bed B. So let’s go ahead and click over. New

scratch paper. And I’m going to go back in and refill in that we’ve already done 630

for Bed A. And now we do the exact same thing for Bed B. You may already have on your cheat

sheet the fact that we have six annuals, we have four perennials, and that we have seven

shrub types. And then we do the same thing because we’re going to have five total flowers

or shrubs in Bed B as well. And so I need to create my situation here. And then the

exact same logic applies. What does it tell us about Bed B however? It said Bed B must

have exactly two types of shrubs. So we’ll start with the shrubs. We’ll place the shrubs

10:00

first. How many shrubs could there be? Seven times … and then once we’ve placed seven,

there are only six left to choose from. But we need to account for the overlap, so we

need to filter out two factorial (2!). And then what else does it tell us? It says two

types of shrubs and one type of annual, right? And so we have our annual. And so our annual

is six, so there are six of those. And then the rest are going to be perennials, right?

And so how many perennials could there be? Four and then three. And 4 times 3 over 2!

and we’re off. That’s it. That’s our math. And again, you use your trusty calculator

that you’re going to be able to use on the Integrated Reasoning section. You multiply

all that out, lo and behold, you get 756. Thank goodness it worked out. It was one of

our answer choices. If it wasn’t, you probably did something wrong and you have a chance

to go back and figure out what you did wrong, but you’d actually fill that in there. And

11:00

then that’s it. You’re off to the races. You filled out Column A. You filled out Column

B. You’re assuming both are correct. You check it and move on. And sure enough, you would

have gotten this two-part analysis question correct because you did the math correct.
