Hope everyone is settling into the rhythm by now.
Week 3 is where GMAT starts behaving a little differently. Less straightforward arithmetic, more thinking.
You’ll see letters instead of numbers. And averages that don’t always play nice.
This is also a good time to attempt your first mock, just to get a feel for the test environment and understand how the exam actually flows.
Weekly time budget: 10 to 15 hours total
Week 3 rules- Quant: still no calculator
- Timing ramp stays the same. Accuracy earns speed, not the other way around.
- Error log is not optional.
- New rule: If your setup looks ugly, stop. GMAT does not reward bravery through bad structure.
It’s time to attempt your first mock: launch it from
mba.comThings to keep in mind:- Allocate 3 hours from your schedule
- Attempt it in a single sitting and take only one break
- Choose the section order you are most comfortable with. The default many people start with is Q / V / DI
What you should focus on during this attempt:Don’t stress if you don’t know everything yet. We are still early in the plan and many topics are still to come.
The goal here is simply to
experience the real test environment and understand how the exam feels.
Pay attention to things like:- Were you able to attempt all the questions?
- Did you blank out at any point during the test?
- What did you do when you encountered a completely new question?
After the test, note down a few key takeaways. We’ll discuss them in more detail before the next mock.
Think about:
- How did you score?
- How far are you from your target score?
- Which sections need the most attention?
- Where can you get the best ROI in the coming weeks?
- How should you structure your prep from here?
Week 3: Linear Algebra + StatisticsThis week is about learning to stay calm when numbers disappear and symbols show up.
Algebra is not hard. What’s hard is panicking the moment you see x and y together.
Statistics is not about formulas.
What this week is really aboutBy the end of Week 3, you should be able to:
- Translate word problems into equations without staring at them for 60 seconds
- Stop over-solving when a simple setup would do
- Understand mean and median behavior instead of memorizing tricks
- Not freak out when standard deviation shows up

Practice Sets:Phase 1: Easy-mode practice Target:
- Either reach 80% accuracy on 20 questions, or
- Build a clean streak of 15 correct
You have two ways to do this. Pick the one that fits how you usually study.
Option A: Manual practice (no Forum Quiz subscription needed)Click the links below, sort by Kudos and solve questions directly on the forum.
Option B: Forum Quiz mode (recommended if you have the subscription)- Build 2 quizzes: (1) Algebra, (2) Statistics
- Goal is the same as Option A: 80% on 20 or a streak of 15
- Do small sets (15 questions). Review after each set.
Timing ramp for Phase 1- Set 1: Untimed (focus on setup and accuracy)
- Set 2: Soft-timed (generous time, still process-focused)
- Set 3: Normal pacing only after accuracy is stable
Phase 2: Official-style questions (only after Phase 1 feels comfortable)Once the practice sets feel comfortable, it's good to start testing yourself on official-style questions:
Target:
- Either reach 90% accuracy on 30 questions, or
- Build a clean streak of 20 correct
Common traps to actively watch forKeep it simple:
- Over-algebraizing something simple
- Forgetting to define variables
- Treating statistics like formula dumping
- Solving aggressively when estimation would work
What’s coming next weekExponents, Roots, Inequalities, and Absolute values
Critical Reasoning - Strengthen and WeakenIf Assumption questions were about finding the missing piece,
Strengthen and Weaken are about asking:
“What would actually help this argument?”
“What would quietly break it?”
What you should get out of this weekBy the end of the week, you should be able to:
- You’ll predict the answer before reading choices more often
- You’ll stop falling for answers that sound smart but do nothing
- You’ll feel more confident eliminating wrong options
- You’ll explain why something strengthens or weakens, not just feel it

What’s coming nextNext Verbal update, we’ll learn more about Evaluate and Find the Flaw questions
This week, DI is not about crunching numbers. It’s about realizing that GMAT often isn’t asking you to calculate anything at all. It’s asking whether you understand what the question is actually demanding.
What we’re focusing on this week- Non-math Data Sufficiency questions
- Yes No logic over numeric manipulation
- Understanding answer choice structure
- Spotting subtle insufficiency even when a statement “feels helpful”

- Combining statements too early
- Treating “more information” as “sufficient information”
- Assuming typical cases instead of testing edge cases
GMAT lives in edge cases. Don’t ignore them.
What’s coming nextGraphs. Numbers are about to move from equations to charts.
