Mastering Calculation Tricks for CAT Aspirants: Strategies for Speed and Accuracy
The Common Admission Test (CAT) is a rigorous examination that challenges students in various domains of mathematics, including quant and data interpretation. One of the key aspects of excelling in these sections is mastering calculation tricks to enhance both speed and accuracy. Here are some valuable tips and tricks recommended for CAT aspirants to improve their calculation skills.
Essential Calculation Tricks for CAT
1. Learn Multiplication Tables and Vedic Mathematics
Start by learning multiplication tables up to 300. This forms a foundational understanding of basic multiplication, which can significantly speed up your calculations. Additionally, delve into Vedic mathematics. Vedic mathematics is a system of mathematics that allows for faster and more efficient calculations. It includes a collection of sutras (techniques) that can be applied to solve mathematical problems in a simpler and quicker way. Trust me, it will transform your approach to calculations.
2. Fractions and Quick Calculations
Practice fractions from 1/2 to 1/15. These fractions are commonly used in topics such as time-speed-distance, work, and ratio and percentage questions. Having a strong grasp of these fractions will allow you to perform quick mental calculations and comparisons. This ability will be instrumental in saving time during the exam.
3. Memorize Squares and Cubes
Memorize the squares of numbers from 1 to 30 and the cubes from 1 to 20. Knowing these values by heart will enable you to solve problems more efficiently, especially those involving quadratic equations, cubic equations, or number series.
4. Never Rely on Calculators
Avoid using calculators unless absolutely necessary. Even though the use of calculators is allowed in the CAT, practicing mental calculations will make you faster and less prone to errors. It is essential to develop the habit of performing calculations mentally, as this skill can significantly boost your overall performance.
Reading Comprehension and Option Analysis
Another crucial aspect of improving calculation and problem-solving speed is efficient reading and option analysis. Always read both the question and the answer choices carefully before starting to calculate any numbers. The options will give you a hint about the level of accuracy required, and this can guide your approach to solving the problem. For example:
Whole Numbers: Fractions such as 3/7 do not require division; you can leave the fraction as is. Decimal Accuracy: For options like 35.3, 358, you need a high level of precision in division. Approximate Values: Options such as 2353, 2355, 2349, 2359 suggest that you only need to calculate the ones and tens place.Additional Tips for Speed Calculation
In addition to the above tricks, here are some more methods to enhance your speed and accuracy in calculations:
Tables Up to 30 Squares up to 30 Cubes up to 10 Triplicates (up to the first five numbers) Vedic Multiplication: Learn these methods online or request additional explanations if needed.Remember, the key to success is not just memorizing these tricks but also applying them in a strategic manner. Always read both the question and the answer choices before you start calculating. This will help you determine the necessary level of precision and speed of your calculations.
Practice these techniques consistently, and over time, you will see a significant improvement in your calculation speed and accuracy. This will not only help in performing well in CAT but also in various other competitive examinations.
