Important Tips to Score High in CAT Arithmetic

1. Avoid Over-Calculation

CAT often tests logic, not heavy calculations. Learn to approximate smartly.

2. Solve Questions Backwards

Options can help you find the answer faster—use reverse substitution.

3. Prioritize High-Yield Topics

Percentages, Ratio-Proportion, Averages, and Speed-Time-Distance dominate the exam.

4. Focus on Accuracy First

Speed comes naturally when concepts are strong. Don’t rush.

5. Analyse Every Mistake

Error analysis is more important than solving 100 extra questions.

Daily 1-Hour Practice Routine

• 20 mins – Concept + formula revision
• 25 mins – Topic-wise practice
• 15 mins – Solve 2–3 CAT-level questions

Following this consistently for 30 days will give you a noticeable improvement in your Quant score.

Conclusion

Mastering Arithmetic for CAT 2026 in 30 days is absolutely achievable with a structured plan. Build strong basics in Week 1, push your skills in Week 2, attempt CAT-level problems in Week 3, and finish strong with mocks in Week 4. With consistent practice and smart strategy, Arithmetic can become your highest-scoring section in CAT 2026.
