🔑 Key Trends & Viral Insights for Your Strategy
This data is your golden ticket. It highlights a massive shift in CAT's focus, especially after the exam pattern changed to 22-26 questions per slot (starting from CAT 2020).
1. Arithmetic is the Unquestioned King (The 99 Percentile Builder) 👑
Consistency is Key: Across all 8 years, Arithmetic remains the most dominant section. Topics like Percentage, SI CI, Instalment, and Time, Speed and Distance (TSD) consistently account for 30-40% of the entire QA paper.
Viral Insight: In CAT 2017 Slot 1, the Percentage, SI CI, Instalment sub-topic alone had 6 questions out of 34! This proves that mastery of this one area is non-negotiable for a high percentile.
2. Algebra's Rise to Prominence (The Difficulty Spiker) 📈
The Big 3: Modulus/Inequality/Max Min/Integral Solutions, Equations, and Progression are the backbone of modern CAT Algebra.
The Modulus/Inequality Spike: This sub-topic saw a massive increase in weightage and difficulty, peaking with 5 questions in CAT 2020 Slot 2. It is the go-to area for IIMs to set tricky, time-consuming questions.
Viral Insight: Since the question count dropped to 22 (from 34), Arithmetic (7-8 Qs) and Algebra (6-7 Qs) together form roughly 70% of the paper. Focus here for maximum returns!
3. The Number System Crash (The Time-Saver) 📉
The Shocking Drop: Historically important topics like Factor Theory, HCF LCM, and Remainder Theorem have seen their weightage plummet, especially from 2020 onwards, often having zero questions per slot.
Viral Insight: Stop spending excessive time on complex Number System problems. Cover the basics (like Divisibility Rules and Factor Theory) but shift your focus completely to application-heavy areas like Arithmetic and Algebra.
4. Geometry and Modern Math (The Reliable Support) 🎯
Geometry's Stability: The Geometry sub-topic is incredibly stable, reliably giving 2-3 questions per slot in most recent years. These are often formula-based and a high-accuracy zone.
Permutations & Combinations (P&C): This topic consistently has 1-2 questions every year, proving it's worth the effort to master the fundamentals.
5. Crafting Your Study Plan for Success
To ensure you are on the right track, it’s essential to have a well-structured study plan. Here’s how you can create one:
Set Clear Goals: Define what you want to achieve in each study session.
Allocate Time Wisely: Divide your time between different topics based on their weightage.
Practice Regularly: Consistent practice is key. Use mock tests to gauge your progress.
Review and Adjust: Regularly assess your performance and adjust your study plan accordingly.
Final Takeaway for CAT 2025/2026: Your Quant preparation should be structured around Arithmetic (Priority 1) and Algebra (Priority 2). Treat Geometry as your reliable third pillar, and approach the Number System with caution, focusing only on the essentials.
