Why Math Is Important in Competitive Exams
Mathematics helps examiners measure a candidate’s:
-
Logical thinking
-
Numerical ability
-
Decision-making power
-
Accuracy under pressure
-
Time management skills
Most competitive exams include sections like:
-
Arithmetic
-
Algebra
-
Geometry
-
Trigonometry
-
Data interpretation
-
Number systems
-
Statistics
A strong foundation can boost your score in all these topics.
1. Master the Basics Before Learning Shortcuts
Many students make the mistake of jumping directly to tricks and formulas. But shortcuts only work when your basics are strong.
Focus on these core basics:
-
Addition, subtraction, multiplication, division
-
Square, cube, square root, cube root
-
Percentages
-
Ratios & proportions
-
Fractions & decimals
-
Basic algebra rules
Once these are solid, solving advanced problems becomes easy and fast.
2. Learn the Most Important Formulas
Competitive exams often require quick calculations. Memorizing essential formulas saves time and improves accuracy.
Must-Know Formula Categories
-
Percentage → Profit, Loss, Discount
-
Simple & Compound Interest
-
Time, Speed, and Distance
-
Work & Wages
-
Algebraic identities
-
Area & Volume formulas
-
Trigonometric identities
-
Permutation & Combination basics
Make a small formula notebook and revise it daily.
3. Practice Mental Math for Speed
Mental math is a secret weapon for scoring high.
Try these daily exercises:
-
Multiplying 2-digit numbers mentally
-
Converting percentages to fractions quickly
-
Estimating sums and differences
-
Memorizing squares up to 30 and cubes up to 15
-
Practicing Vedic Math techniques
The goal is to increase speed without sacrificing accuracy.
4. Use Smart Techniques for Common Problems
✔️ Percentage Shortcut
To find X% of a number, break it down:
For example, 18% of 250
= 10% (25) + 8% (20)
= 45
✔️ Multiply faster
45 × 99
= 45 × (100 – 1)
= 4500 – 45
= 4455
✔️ Time and Speed Trick
If speed increases by 20%, time decreases by:
Decrease = 20 / (1 + 20/100) = 16.67%
✔️ Simple Interest
SI = (P × R × T) / 100
These shortcuts make problem-solving much more efficient.
5. Solve Previous Year Questions
Every competitive exam repeats patterns. Solving last 5–10 years' question papers helps you understand:
-
Frequently asked topics
-
Difficulty level
-
Time required per question
-
Most-used formulas
-
Common trick questions
This method alone can increase your score by 30–40%.
6. Practice Topic-Wise Before Full Mock Tests
Don’t jump into full mock tests immediately. First practice each topic separately.
Recommended sequence:
-
Learn theory
-
Practice easy questions
-
Solve medium-level problems
-
Try advanced problems
-
Finish with chapter-wise timed quizzes
Then move to full-length mock tests once your accuracy is above 80%.
7. Focus More on High-Scoring Topics
Some topics have higher weight in almost every exam.
High-Scoring Topics Worldwide:
-
Percentage
-
Ratio & Proportion
-
Profit & Loss
-
Simple & Compound Interest
-
Time & Work
-
Time, Speed & Distance
-
Data Interpretation
Give these 60–70% of your practice time.
8. Learn to Use Approximation
In competitive exams, exact calculation is not always required. Sometimes a smart approximation saves time and gives the correct option.
For example:
103 × 48 ≈ 100 × 50 = 5000
If options are far apart, you get the right one instantly.
This is especially useful in Data Interpretation.
9. Manage Time With 3-Step Strategy
Time management decides your final score. Use this strategy:
✔️ Step 1: Easy questions first (40% time)
Solve all straightforward questions quickly.
✔️ Step 2: Medium questions next (40% time)
Use logic and shortcuts.
✔️ Step 3: Hard questions last (20% time)
Attempt only if time remains.
This reduces stress and increases marks.
10. Don’t Get Stuck on Any Question
If a problem seems difficult:
-
Skip it temporarily
-
Mark it for review
-
Come back after completing the easy ones
One tough question should not reduce your entire score.
11. Use Mock Tests to Improve Accuracy
Full-length mock tests help you:
-
Understand exam pressure
-
Improve speed
-
Reduce silly mistakes
-
Build confidence
Analyze each test:
-
Why mistakes happened
-
Weak topics
-
Time-wasting steps
Correcting these gives quick improvement.
12. Keep a “Mistake Notebook”
Whenever you make a mistake, write:
-
The question
-
Why the mistake happened
-
The correct method
Reviewing this notebook weekly prevents repeating the same mistakes.
13. Stay Consistent With Daily Practice
Practice for at least 1–2 hours daily. Consistency matters more than long study sessions.
Daily Checklist:
-
10 easy questions
-
10 medium questions
-
5 difficult questions
-
1 speed test
-
Formula revision
This routine guarantees improvement.
14. Build Confidence Through Revision
Revision is the key to scoring high. Without revision:
-
Formulas fade
-
Speed slows down
-
Mistakes increase
Revise weekly and monthly.
Conclusion
Math for competitive exams is not about talent; it is about the right strategy, daily practice, and smart shortcuts. If you strengthen your basics, learn formulas, solve previous papers, and take mock tests regularly, you can easily score high.
Mathematics rewards practice — the more you solve, the better you become.
