2. Simplification and Approximation

These questions are scoring opportunities. They test your ability to use BODMAS rules and Vedic math techniques. By memorizing squares up to 30, cubes up to 20, and fractions to percentage conversions, you can solve these in seconds.

3. Number Series

Whether it is missing number series or wrong number series, this topic tests your pattern recognition skills. Practice common patterns like squares, cubes, prime numbers, and differences of differences to stay ahead.

4. Quadratic Equations

These are straightforward and involve finding the roots of equations. Once you master the sign-convention method, you can solve these questions in under 30 seconds per set.

5. Arithmetic: Percentages

Percentages are the foundation for Profit & Loss, Simple Interest, Compound Interest, and Data Interpretation. A strong grasp of percentage change and base values is non-negotiable.

6. Ratio and Proportion

This topic is essential for solving Mixture and Alligation as well as Partnership problems. Understanding how to distribute values based on specific ratios is a core skill for banking math.

7. Profit, Loss, and Discount

• Focus on Speed: Banking exams are tests of speed. Use timers for every practice set.
• Mock Tests: Take full-length mock tests to simulate exam conditions and analyze your weak areas.
• Analyze Errors: Don't just check your score; review every question you got wrong to understand the concept you missed.
• Consistency is Key: Dedicate specific time slots for calculation practice, such as mental multiplication and division.

By prioritizing these top 10 topics, you can streamline your preparation and significantly increase your chances of clearing the IDBI Executive cut-off. Remember, accuracy is just as important as speed—avoid guessing to prevent negative marking.
