It is a very competitive examination called the National Talent Search Examination (NTSE) which recognizes and nurtures talented students all over India. However, the NTSE Mathematics section is quite difficult and vast. With a focus on appropriate topics and mastering the concepts, one can crack the exam with a good score in Mathematics. Key topics to Prioritize while preparing for the NTSE Mathematics paper.

• Algebra

Algebra is a key part of the NTSE Mathematics paper, and you will find multiple questions on this topic in the examination. Some of the crucial sub-topics to be stressed are as follows:

• Linear Equations: Solve systems of linear equations in one or two variables using elimination or substitution.

• Quadratic Equations: Be familiar with the procedure to solve quadratic equations and the practical application of the quadratic formula.

• Polynomials: Factoring polynomials, the roots of polynomials and the fundamental theorem of algebra.

• Progressions: Both Arithmetic Progression (AP) and Geometric Progression (GP), their terms, and sum formulas are studied for the nth term.

These ideas do not just help crack simple questions but also make it easy for you to solve complicated word problems during the competition.

• Number Theory

Number Theory is a key area where many NTSE examinees are worried about how to deal with this part of the question. Areas that require more attention are:

• Divisibility Rules: Master the divisibility rules for the numbers 2, 3, 5, 9, and 11 to solve this problem.

• Prime Numbers and Factorization: Elementary idea of prime factorization and prime numbers.

• LCM and HCF: Methods to compute the Least Common Multiple (LCM) and Highest Common Factor (HCF) of two or more numbers.

• Remainder Theorem: This is a useful technique for solving problems involving divisibility and the law of modular arithmetic.

Getting a deep understanding of number theory will make it easier for you to work with problems that involve the topics of divisibility, remainders, and factors.

• Geometry

Geometry is another fundamental topic in NTSE Math. It is about differentiate that are relevant to sizes, shapes, and spatial relationships. The key sub-topics include:

• Mensuration: The areas and volumes of geometric figures such as squares, rectangles, circles, triangles, spheres, and cones. Learn the formulas and the way to apply them carefully.

• Coordinate Geometry: The basics of the Cartesian plane, the formula for the distance, the section formula, and the mid-point theorem.

• Angles and Triangles: Properties of angles, parallel lines, angle bisectors, and triangles (like congruence and similarity).

The geometry problems are sometimes quite difficult, but when you feel secure with the underlying principles and formulas, they become much easier to solve. NTSE test series at regular intervals also makes it easy.

• Trigonometry

While the NTSE Mathematics syllabus does not cover advanced trigonometry, one should be familiar with basic trigonometric concepts, as they are usually part of the problems connected with angles and triangles. Taking the NTSE mock test will help you understand the types of questions that are usually asked.

• Trigonometric Ratios: Sine, cosine, tangent, etc., and their relationships.

• Basic Identities: Pythagorean identities, and the basic addition/subtraction formulas.

• Heights & Distance: When one uses the trigonometric ratios to solve the height or distance problems.

Trigonometry questions are commonly found in word problems, notably in the sections related to geometry.

• Probability and Statistics

Probability and Statistics are the pivotal issues in the NTSE Mathematics exam, as they essentially test logical thinking and data interpretation skills.

• Probability: Basic, like the cases: outcomes, which are not results of events, and the few mathematical probability formulas (P(E) = Number of favourable outcomes / Total outcomes).

• Statistics: Measures of the central tendencies are namely the mean, median, and mode, with use of them, and their applications, if the file is not too large. Unquestionably, you need to deal with the data visualization using bar graphs and histograms in the following section.

• Mensuration

Mensuration (or measurement) is one of the chapters which is quite important both in the syllabus of the 9th and the 10th class, in the NTSE exam. You need to focus on:

• Surface Areas and Volumes: Three-dimensional figures e.g. thick, long barrels, cones, and spherical surfaces.

• Areas of Plane Figures: Circles and circular areas of a certain fraction, as well as the parts contained by lines on the figure.

How to solve difficult problems through these methods will make you the fastest and the most correct in the exam.

• Miscellaneous Topics

Aside from the core subjects, other crucial sections require attention:

• Ratio and Proportion: Calculate the problems on direct and inverse proportions.

• Linear and Non-Linear Graphs: Analyzing and plotting graphs consisting of linear and quadratic equations.

• Set Theory: Basic set operations, Venn diagrams, and their applications explanations are some of the topics taught at schools.

• Let’s Wrap Up

The NTSE Mathematics exam comprises a lot of subjects but keeping your eyes on the above-mentioned subjects will help you to score better in the exam. Six key areas most of which need to be practiced well include algebra, number theory, mensuration, trigonometry, geometry and probability. Practice regularly but with a positive approach, strengthen your basics and practice a lot so that you can do well in the NTSE Mathematics section.
