Hello, aspiring champions of competitive exams!

As a seasoned math coach with 13 years of experience and the founder of Welcome2Maths, I've seen first-hand how mastering mathematics can be a game-changer in competitive exams. Today, I want to share some invaluable techniques and insights that can help you ace the math section of any competitive exam. Whether you’re preparing for engineering entrance exams, banking exams, or any other competitive tests, these strategies will be your secret weapon.

Understanding the Importance of Speed and Accuracy

In competitive exams, time is of the essence. You need to solve complex problems quickly and accurately. This requires not only a strong understanding of mathematical concepts but also the ability to apply shortcuts and techniques that save time.

Technique 1: The Power of Estimation

Estimation is a powerful tool that can help you quickly gauge the range of possible answers. For instance, when dealing with large numbers or complex calculations, rounding them to the nearest ten or hundred can simplify the problem significantly. This way, you can eliminate obviously incorrect options and improve your chances of choosing the right one.

Technique 2: Simplifying Fractions and Percentages

Understanding how to quickly simplify fractions and percentages is crucial. For example, knowing that 25% is the same as one-fourth or that 50% is half can speed up your calculations. Practicing these conversions regularly will make them second nature during exams.

Technique 3: The Magic of Vedic Maths

Vedic Maths is an ancient system that offers a variety of techniques to simplify mathematical operations. In my course, "Vedic Maths for Competitive Exams" at Welcome2Maths, we delve deep into these techniques. Here are a couple of my favorites:

The Vertically and Crosswise Method: This technique is perfect for multiplying large numbers. Instead of the traditional long multiplication, you can multiply numbers vertically and crosswise, which is often quicker and more intuitive.
The Base Method: This method is excellent for squaring numbers close to a base, like 10, 100, or 1000. For example, to square 98, you recognize that it is 2 less than 100. You then use the formula (Base - Difference)^2 = Base^2 - 2(Base * Difference) + Difference^2, which simplifies to 98^2 = 9604.

Technique 4: Breaking Down Complex Problems

Often, complex problems can be broken down into simpler parts. This method not only makes the problem more manageable but also reduces the likelihood of making errors. For instance, in algebra, breaking down equations into smaller, solvable steps can save time and increase accuracy.

Technique 5: Memorizing Key Formulas and Shortcuts

Having key formulas and shortcuts at your fingertips is essential. Create a cheat sheet of important formulas, theorems, and shortcuts, and review it regularly. This practice will ensure that you can recall them quickly during the exam

Technique 6: Practicing with Mock Tests

One of the best ways to prepare for competitive exams is by practicing with mock tests. This not only familiarizes you with the exam pattern but also helps you identify areas where you need improvement. At Welcome2Maths, we offer a variety of mock tests that can help you hone your skills and build confidence.

Conclusion

Mastering maths for competitive exams is all about blending knowledge with strategy. By incorporating these techniques into your study routine, you can enhance your speed and accuracy, making you well-prepared for any challenge. Remember, consistent practice and a positive mindset are key to success.
