Error Log & Analytics

Tracking system · every week

The same tracking system runs across all 12 weeks: log every miss, review the pattern, redo it. Two tools, one daily habit.

Minimum fields to track

Use the built-in error log tracker above, the Analytics portal, or a customized Excel/Google Sheets spreadsheet, whichever you'll actually keep up with.

  • Topic:

    fractions, ratios, percent, CR conclusion, etc.

  • Error type:

    concept gap / setup error / calculation slip / rushed reading.

  • Trigger:

    what in the prompt pulled you off track.

  • Fix:

    one-sentence rule you will apply next time.

Redo rule

Redo rule: redo every missed question after a fixed frequency (recommended: after each week) without looking at the solution.

Analytics: what to check before wrap-up

  • Accuracy by topic: which sub-skills are still under 80%.
  • Timing by topic: where you're consistently over 2 min/question.
  • The trend across your last few sessions, not just one bad day.

Week 3 Overview & Rules

Group Rules

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

It’s time to attempt your first mock: launch it from mba.com

Open

Things 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

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.

What you should focus on during this attempt

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?

Think about

After the test, note down a few key takeaways. We’ll discuss them in more detail before the next mock.

  • 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 + Statistics

Quant Track

This 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 about

By 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

Common traps to actively watch for

Keep it simple:

  • Over-algebraizing something simple
  • Forgetting to define variables
  • Treating statistics like formula dumping
  • Solving aggressively when estimation would work

Critical Reasoning - Strengthen and Weaken

Verbal Track

If 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 week

By 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

Data Insights

DI Track

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”

Focus only on:

  • Answering a different question than the one asked
  • 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.
