Because the Rashtriya Military Schools (RMS) and Sainik Schools (AISSEE) entrance exams are strictly objective (OMR-based), the mathematics preparation must pivot entirely toward speed, accuracy, and shortcut techniques.
Here is the exhaustive Mathematics syllabus for both the Class VI and Class IX entry levels
Part I: Class VI Entrance Syllabus
This level tests a student’s grasp of foundational arithmetic and their ability to solve multi-step word problems quickly.
1. Number System & Arithmetic
- Numbers: Place value, face value, Indian and International systems, rounding off, and Roman numerals.
- Operations: Addition, subtraction, multiplication, and division. Deep focus on the BODMAS rule.
- Factors and Multiples: Prime and composite numbers, prime factorization.
- Divisibility Rules: Complete mastery of rules for 2 through 11 to instantly eliminate wrong options in OMR sheets.
- HCF and LCM: Application in word problems (e.g., bells tolling together, traffic lights).
2. Fractions & Decimals
- Types of fractions (proper, improper, mixed, equivalent).
- Conversion between fractions and decimals.
- Addition, subtraction, multiplication, and division of fractions and decimals.
3. Commercial Mathematics (High Weightage)
- Unitary Method: Foundational concept for all commercial math.
- Ratio and Proportion: Simplification of ratios and dividing quantities.
- Percentages: Converting fractions/decimals to percentages and vice versa.
- Profit and Loss: Calculating profit/loss amounts and percentages (Cost Price, Selling Price).
- Simple Interest: Direct application and finding the amount.
- Average: Calculating the mean of given observations.
4. Measurements & Geometry
- Metric System: Conversion of units for length, mass, and capacity.
- Time and Temperature: 12/24-hour clock formats, elapsed time, and converting between Celsius and Fahrenheit.
- Time, Speed, and Distance: Calculating speed, converting km/hr to m/s, and basic train problems.
- Basic Geometry: Concepts of points, lines, line segments, rays, and types of angles (acute, right, obtuse, straight, reflex).
- Mensuration: Calculating the perimeter and area of squares and rectangles.
- Circles: Identifying the center, radius, diameter, and chord.
Part 2: Class IX Entrance Syllabus
This level introduces algebra, advanced geometry, and more complex commercial math. It requires a firm grasp of formulas and algebraic identities.
1. Advanced Number System
- Rational Numbers: Properties (closure, commutativity, associativity), representation on a number line, and finding numbers between two rational numbers.
- Squares and Square Roots: Finding roots using prime factorization and long division methods.
- Cubes and Cube Roots: Properties of perfect cubes and finding cube roots.
- Exponents and Powers: Laws of exponents , negative exponents, and standard form/scientific notation.
2. Algebra
- Algebraic Expressions: Addition, subtraction, and multiplication of polynomials.
- Standard Identities
- Factorization: Using common factors, regrouping, and standard identities.
- Linear Equations in One Variable: Solving complex equations and formulating equations from word problems.
3. Advanced Commercial Mathematics
- Comparing Quantities: Successive discounts, VAT/GST calculation.
- Compound Interest: Calculating interest compounded annually and half-yearly
- Direct and Inverse Proportion: Advanced unitary method applications.
- Time and Work: Problems involving multiple individuals working together or alternately.
4. Geometry & Mensuration
- Lines and Angles: Intersecting lines, transversal properties (alternate, corresponding, co-interior angles).
- Polygons and Quadrilaterals: Angle sum property, exterior angles, and properties of parallelograms, rhombuses, rectangles, squares, and kites.
- Triangles: Congruence, Pythagorean theorem.
- 2D Mensuration: Area of parallelograms, triangles, trapeziums, and circles
- 3D Mensuration: Surface area and volume of cubes, cuboids, and right circular cylinders.
5. Data Handling & Statistics
- Central Tendency: Calculating Mean, Median, and Mode specifically for ungrouped data.
- Data Interpretation: Reading and constructing frequency distribution tables, bar graphs, double bar graphs, and pie charts.
- Probability: Calculating the experimental probability of a single event (e.g., coin tosses, rolling dice).
