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 6 Overview & Rules

Group Rules

Hope you’re settling into the flow by now.

This week is not about anything being individually difficult, but things can go wrong quickly if you lose track midway. You’ll see multiple groups, multiple conditions, and questions where a lot is happening at once. If you try to hold everything in your head, it usually falls apart.

So the focus this week is simple: stay structured. Draw things out, organize information, and don’t rush into solving.

Also, plan to take your second official mock at the end of this week. This one is important, it will give you a much clearer picture of your progress and where you still need to improve.

Weekly time budget: 15 to 20 hours total

Week 6 rules (so the group stays aligned)

  • Quant:

    no calculator

  • Timing ramp still applies

  • Error log continues

  • New rule:

    If the problem has more than two moving parts, draw something before solving. Head math will betray you here.

Week 6: Overlapping Sets | Mixtures (Weighted Averages) | Sequences

Quant Track

This is the week where putting things on paper actually makes life easier. Circles, arrows, diagrams, or any structure that helps you keep track.

None of these topics are too hard individually. It just gets messy when you try to mentally calculate everything.

What this week is really about

By the end of Week 6, you should be able to:

  • Automatically draw Venn diagrams for overlapping sets
  • Stop guessing overlaps and start defining them
  • Treat mixtures as weighted averages, not algebra puzzles
  • Recognize sequences early instead of brute-forcing terms
  • Know when formulas help and when they don’t

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
  1. Set 1: Untimed

    (focus on setup and accuracy)

  2. Set 2: Soft-timed

    (generous time, still process-focused)

  3. Set 3: Normal pacing

    only after accuracy is stable

Phase 2: Official-style questions (only after Phase 1 feels comfortable)90% accuracy on 30 questions or a streak of 20 correct

Once the practice sets feel comfortable, it's good to start testing yourself on official-style questions:

Common traps to actively watch for

  • Trying to 'see' overlaps instead of drawing them
  • Forgetting that totals include overlaps
  • Treating mixtures as simple averages
  • Forcing formulas onto sequences that don’t need them

Structure beats speed here. Every time.

What’s coming next week

Combinations, Probability and Min-Max

Reading Comprehension – Main Purpose

Verbal Track

This week, RC is about zooming out and understanding the overall idea.

Don’t worry too much about details or traps. The main question you should keep asking is, why did the author write this?

What you should get out of this week

By the end of the week, you should be able to:

  • You’ll identify the author’s intent more quickly
  • You’ll stop confusing tone with purpose
  • You’ll eliminate answer choices that are too narrow or too extreme
  • You’ll feel more comfortable summarizing passages in one line

Phase 2: Official-style questions (only after Phase 1 feels comfortable)

We’ll pick up official-style questions next week once we’ve gone through the common RC question types. For now, just focus on getting the basics right.

Focus On

For each passage:

  • Write one sentence on why the passage exists
  • Ignore tempting detail-heavy answer choices
  • Check if the answer matches the entire passage, not one paragraph
What's Coming Next

Multi-Source Reasoning (MSR)

DI Track

We now come to the nemesis of many test takers, MSR. Lots of data, multiple tabs, charts everywhere, and questions that feel heavier than they look. It’s also one of the biggest time sinks in DI.

This is not about speed reading. It’s more about how you navigate the information.

If you try to read everything, you’ll run out of time. If you jump between tabs without a plan, you’ll miss context.

Second Mock & Analysis

Mock
By the end of this week, plan to take your second official mock

By the end of this week, plan to take your second official mock.

Open

At this point, we are far enough into the prep that the mock should not just be used for experience. It should help you understand your gap areas properly and show you where your next few weeks need to go after wrapping up the basics. After the test, do not just look at the total score and move on. Spend proper time analyzing it.

Track the following in your error log:

Overall performance

  • Total score
  • Sectional scores
  • Target score vs current score
  • Gap remaining overall and section-wise

Timing analysis

  • Were you able to finish all questions in each section?
  • On which questions did you overspend time?
  • Did you rush at the end of any section?
  • Did you guess because of lack of time or lack of clarity?

Accuracy analysis

  • Easy questions missed
  • Medium questions missed
  • Hard questions missed
  • Questions you got right but were not confident about
  • Questions you got wrong even after spending a lot of time

Question type / topic analysis

  • Quant:

    Which topics are still leaking points? Are you losing marks more in setup-heavy questions or calculation-heavy questions?

  • Verbal:

    Are you struggling more with CR or RC? In CR, which question types are hurting you? In RC, is the issue passage structure, main point, or detail questions?

  • DI:

    Which formats are taking the most time? Are mistakes coming from logic, calculations, or missing conditions?

Behavioral analysis

  • Did you blank out at any point?
  • Did stress affect your reading or judgment?
  • Did you keep changing answers too often?
  • Were you mentally tired by the last section?
  • Was your section order working for you or not?

Takeaways to write down

After analysis, write 4 things clearly:

  • Top 3 score blockers right now
  • Topics that need the most work over the next few weeks
  • One timing habit you need to fix
  • One thing that actually went well and should be continued

That way, the next few weeks of prep become much more targeted and you stop improving randomly.
