In the final month of CAT prep, your Quantitative Aptitude score doesn't improve from learning new concepts. It improves from drilling your high-yield topics, building speed on familiar problems, and mastering your question selection strategy. I've seen students try to 'fill gaps' in the final month by learning obscure geometry theorems or advanced number theory. They waste time and confuse themselves. Meanwhile, the students who focus on arithmetic, algebra, and TITA strategy usually see the steadiest QA gains. This is your final-month QA roadmap.
Let me be specific about which topics matter, how to drill them, and the mental framework that separates 85%ile QA scorers from 95%ile scorers.
Your QA High-Yield Topics Priority Table
| Topic | Frequency in CAT | Difficulty | Time Per Question | Final-Month Focus |
|---|---|---|---|---|
| Arithmetic (Profit Loss, Percentages, Ratios, SI/CI) | Very High | Low-Medium | 1-1.5 min | SPEED DRILLS |
| Algebra (Equations, Functions, Inequalities) | High | Medium | 1.5-2 min | SPEED DRILLS |
| Numbers (Divisibility, LCM/GCD, Primes) | Medium (10-15%) | Low-Medium | 1-2 min | CONCEPT REINFORCEMENT |
| Geometry (Triangles, Circles, Mensuration) | Medium (10-15%) | Medium-High | 2-3 min | SELECTIVE DRILLS |
| Advanced Topics (Probability, Permutations) | Low (5-10%) | High | 3+ min | SKIP FOR NOW |
Notice the distribution: Arithmetic and Algebra make up 50-60% of CAT QA. These are your high-yield topics. If you master these two, you're already at 50%ile in QA. The final month focus: get faster at arithmetic and algebra.
Don't learn new advanced topics in the final month. If you haven't learned permutations by now, skipping it entirely on exam day will hurt you less than spending 20 minutes confused on a probability question.
Your Arithmetic Speed Drill Protocol
Arithmetic questions are straightforward — high frequency, moderate difficulty, and quick to solve if you're trained. Your final month: drill arithmetic for speed.
- Week 1-2: Solve 10-15 arithmetic questions daily (profit/loss, percentages, ratios, SI/CI). Time yourself: aim for 90 seconds per question average. Track your time and accuracy.
- Week 3: Reduce to 8-10 questions daily. Target: 75 seconds per question average with 90%+ accuracy.
- Week 4: Light maintenance — 5 arithmetic questions daily. Maintain your speed and confidence.
The goal: solve each arithmetic question in 60-90 seconds with high accuracy. At this speed, you can attempt 16-18 QA questions in 40 minutes, which is your target for 99%ile QA.
Algebra: The Speed-Accuracy Balance
Algebra questions range from simple equation-solving to complex function problems. Your final-month strategy differs by sub-topic:
- Linear Equations: These are quick-win questions. Solve 5-10 daily, target 90 seconds per question.
- Quadratic Equations & Functions: Medium difficulty. Solve 3-5 daily, target 2 minutes per question. These require careful setup.
- Inequalities: Often confused by students. Solve 3-5 daily. The trick: always test values. 90 seconds per question is realistic.
- Complex Algebra (Higher-degree polynomials, Logarithms): Skip unless you're already 95%ile. Not worth the time investment.
For algebra, accuracy matters more than speed. Getting 4 out of 5 algebra questions correct in 8 minutes is better than 3 out of 5 in 6 minutes. Build speed gradually while maintaining accuracy.
Numbers & Divisibility: Maintain, Don't Learn
If you've prepared well, you've already learned number properties, GCD/LCM, and divisibility rules. The final month: maintain this knowledge with 5 questions per week. Don't try to 'improve' on a weak topic here. Your time is better spent on arithmetic and algebra.
Geometry: The Selective Approach
Geometry questions are high-difficulty and time-consuming. Many students avoid them entirely in the final month. I recommend: skip new geometry learning, but drill geometry types you're already comfortable with.
- If You're Comfortable with Circle Problems: Solve 2-3 circle questions weekly. These are often solvable in 2-2.5 minutes with practice.
- If You're Weak in Geometry: Skip geometry entirely. Every minute you spend on a geometry question is a minute not spent on arithmetic (which you solve faster and more accurately).
Your goal in QA is to maximize questions attempted with high accuracy, not to know all topics equally.
Your QA Error Log: Identifying the Leak
Maintain a simple QA error log:
| Question Type | Topic | Error Type | Time Taken | Learning |
|---|---|---|---|---|
| QA-5 | Profit Loss | Calculation Error | 2.5 min | Check my percentage calculation formula |
| QA-18 | Algebra | Conceptual | 3+ min | Didn't recognize this as a quadratic. Practice type recognition. |
| QA-22 | Geometry | Time Pressure | 4 min (attempted) | Skipped correctly — should have abandoned at 2 min |
Review every 3 days. If you're making calculation errors in arithmetic, spend a day on mental math drills. If you're slow on algebra, practice factorization. Pinpoint and fix your leak.
Your Formula Sheet: Build It by Week 3
By the start of Week 3, compile a one-page formula sheet with:
- Profit Loss: SP = CP + Profit, Profit % = (Profit / CP) × 100
- SI/CI: SI = PRT/100, A = P(1 + R/100)^n
- Percentages: Common percentage shortcuts (25% = 1/4, etc.)
- Algebra: Quadratic formula, sum/product of roots
- Geometry: Circle (πr², 2πr), Triangle (1/2 × base × height), key Pythagoras relationships
Spend 5 minutes daily reviewing this sheet in Weeks 3-4. This prevents formula amnesia on exam day.
TITA Strategy: Your Final Secret Weapon
TITA (Type In The Answer) questions appear on every CAT and often trip up students. TITA questions don't have answer choices — you have to type your answer. This is both a curse and a blessing.
TITA Advantages:
- No negative marking (TITA carries 0 if incorrect, but no -1 penalty like MCQs)
- You can use trial-and-error if you're stuck
TITA Strategy:
- Attempt TITA questions if you can solve them quickly. A correct TITA answer is worth 3 marks with no penalty for attempting.
- If you're unsure, don't guess. Leave it blank. No negative marking means blank = safe.
- The 1.5-minute rule: If you can't solve a TITA in 1.5 minutes, leave it blank and move on.
In the final month, practice 5-10 TITA questions weekly. These differ in format from MCQs, so practice builds confidence.
Your Final-Month QA Time Allocation
| Week | Daily Drills | Sectional Mocks | Focus |
|---|---|---|---|
| Week 1 | 15 Arithmetic + 8 Algebra + 3 Others = 26 questions | 2 QA sectionals | Build speed baseline, track timing |
| Week 2 | 12 Arithmetic + 6 Algebra + 2 Others = 20 questions | 2-3 QA sectionals | Increase speed, aim for 90 sec/arithmetic, 2 min/algebra |
| Week 3 | 10 Arithmetic + 5 Algebra + 2 Others = 17 questions | 2 QA sectionals | Consolidate speed, build formula sheet |
| Week 4 | 5 Arithmetic + 3 Algebra = 8 questions (light) | 1 final QA sectional | Mental conditioning, confidence |
The Mental Shift: Selective Difficulty
Here's the mindset for final-month QA: You will not solve all 22 QA questions, and that's okay. Your goal is 16-18 questions attempted with 85%+ accuracy. This scores 65-70%ile in QA, which translates to 85-90%ile overall CAT.
If a question takes more than 2 minutes and you're not confident, skip it. Don't get stuck. Move on and attempt 2-3 other questions in that time. This is the difference between an 85%ile scorer (tries all 22, gets 50%) and a 95%ile scorer (attempts 17, gets 85%).
In the final week, your mantra is: 'Fast on my strengths, smart skip on my weaknesses.' Execute this on exam day and watch your QA percentile climb. For deeper QA strategy, check out our CAT Preparation While Working: The 2-Hour-Day Math guide for time-efficient practice.

Frequently Asked Questions
How much time per day should I spend on QA in the final month?
Aim for 30-40 minutes daily in Weeks 1-2 (drills + analysis), reducing to 20 minutes in Week 3, and 10-15 minutes in Week 4. This includes timed practice and error analysis. Don't overstudy — quality focused practice beats hours of unfocused work.
Should I learn new QA topics in the final month if I'm weak in them?
No. If you're weak in a topic you haven't mastered yet (e.g., advanced probability), skip it entirely in the final month. Focus on mastering 70% of QA (arithmetic, algebra, basic numbers) rather than struggling with advanced topics. A 70% mastery with speed beats 50% mastery of all topics.
How do I improve my calculation speed for arithmetic?
Three tactics: (1) Practice mental math — square roots, percentages, common ratios. Spend 5 minutes daily on this. (2) Learn approximation techniques — rounding, estimation. (3) Use shortcuts: 25% = 1/4, 33.33% = 1/3, etc. These habits, built daily, double your calculation speed over 4 weeks.
What's my strategy if I get stuck on a QA question during the exam?
Use the 2-minute rule: if you haven't solved or nearly solved the question in 2 minutes, abandon it. Mark it for later (if TITA, leave blank). Move to your next high-confidence question. Circling back to hard questions in your last 5 minutes (after attempting all easy questions) is the right tactic, not wasting time upfront.
Should I focus on speed or accuracy in the final month?
Both, but accuracy first. Build accuracy to 85%+ on your drills, then gradually increase speed. A slow, accurate approach beats a fast, error-prone one. In the final month, you're aiming for 'fast and accurate,' which comes from drilling familiar topics repeatedly, not learning new ones.
