What you need
Steps
Start with the basics: memorise multiplication tables up to 20, squares up to 30 and cubes up to 15. Write them out daily until you can recall each one without thinking.
Learn the squares of consecutive numbers and numbers near a base, such as 31 squared or 49 squared. These patterns save you from long multiplication.
Add short tricks: convert common percentages to fractions (12.5% is 1/8, 16.66% is 1/6) and use Vedic shortcuts for numbers near 100.
Practise simplification and approximation in timed sets. Round each number to a convenient value, then check how close your estimate is to the answer options.
Work through number series and arithmetic questions with a stopwatch, giving each question a fixed limit of 30 to 45 seconds.
Do 20 to 30 minutes of timed calculation practice every day using a rank file or question set. Record your score and total time after each session.
Review every wrong answer the same day. Note the trick you missed, then repeat that question type at the start of your next practice session.
Tips and common mistakes
Accuracy comes before speed, so slow down until your answers are consistently correct.
Keep a one-page sheet of the fraction and percentage conversions you use most and revise it daily.
Do not skip the fundamentals to jump to tricks; shortcuts only work when tables and squares are automatic.
Use a timer in every practice session so you get used to exam pressure.
Questions
How long before my calculation speed improves?
It depends on your starting point, but daily practice of 20 to 30 minutes usually brings noticeable gains within a few weeks. Consistency matters more than long sessions.
Should I learn tables up to 20 or 25?
Tables up to 20 cover most bank exam calculations. Extend to 25 once the basics feel automatic and you want extra speed.
Can I use a calculator in the exam?
Bank exams do not allow calculators, so do all your practice mentally or on rough paper. That is the skill the exam tests.
