Error Log & Analytics
Tracking system · every weekThe 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 8 Overview & Rules
Week OverviewBe proud of yourself if you’ve made it through the last 7 weeks of this core knowledge build-up.
This is the last week of new topics. Along with working on these, try to get comfortable with anything that still feels shaky. If something didn’t fully click earlier, go back and spend a bit more time on it.
Keep things simple and focus on getting the basics right.
We’ll be taking our third official mock next week, so try to cover any missing areas and go in with as much clarity as possible.
Weekly time budget: 15 to 20 hours total
Week 8 rules
Don't start calculations before understanding the question
Use options in DI, instead of treating it as a pure math question
Step back and rethink instead of forcing one method
Look out for simpler approach instead of over-solving
Week 8: Coordinate Geometry and Word Problems
Quant TrackThis week we are covering coordinate geometry and word problems.
Neither of them is "hard" in the traditional sense, like nobody is asking you to do crazy calculations. The issue is usually that people misread the question or misset it up, and then the math goes wrong from there.
So a big part of this week is just learning to read the problem properly and setting up the structure before you start solving the question.
What this week is really about
By the end of Week 8, you should be able to:
- Feel comfortable plotting points and interpreting slopes
- Know when coordinate geometry is just algebra in disguise
- Translate word problems into equations without losing variables
- Avoid solving the wrong thing because of rushed interpretation
- Sketch more and panic less
Core reads
Why geometry? Geometry is not a standalone topic in the current GMAT Quant syllabus. However, you may still encounter coordinate-plane concepts and geometry-adjacent reasoning within algebra- or graph-based questions, so focus on the basics rather than traditional geometry formulas.

Phase 1: Easy-mode practice80% accuracy on 20 questions or a streak of 15 correct
You have two ways to do this. Pick the one that fits how you usually study.
Forum = Click the links below, sort by Kudos and solve questions directly on the forum. Quiz = preset Forum Quiz (subscription or rewards points).
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
Common traps to actively watch for
- Solving algebraically when a sketch would clarify things
- Losing track of variables in long word problems
- Assuming straight lines where curves exist
- Answering what you think the question asked
Critical Reasoning - Boldface | Discrepancy (Resolve the Paradox)
Verbal TrackThis week in CR, we'll cover boldface and discrepancy questions.
They're a bit different, you need to focus more on how the argument in structured and what each part is doing.
If you get that right, the answers become much easier to narrow down.
What you should get out of this week
By the end of the week, you should be able to:
- You’ll identify roles of statements instead of rereading content
- You’ll stop reacting emotionally to confusing arguments
- You’ll treat boldface like a matching exercise, not a reading test
- You’ll approach discrepancies by asking "how can both be true?"

One mental check to keep repeating
- Boldface: label each bold part before looking at choices, then match roles, not wording
- Discrepancy: ask "how can both statements be true?" and eliminate answers that only explain one side
Different questions. Different standards.
Two-Part Analysis
DI TrackAnother difficult part of DI is TPA.
The questions can get quite lengthy, with multiple combinations to think through, and it’s easy to burn too much time checking every possibility. So the key here is to be smarter with your approach, quickly convert the word statements into equations or relationships, and use the given options well instead of trying to brute-force everything.

End-of-week self-check
Focus on:
- Solving each part independently
- Verifying combinations carefully
- Not letting Part 1 bias Part 2
TPA punishes assumption bleed. Stay clean.
