CXC, CSEC Past Papers

Are you preparing for the CSEC Mathematics exam?   Here's a quick guide to help you understand what the syllabus covers and how to study effectively. 🧮 Main Topics Covered The CSEC Mathematics syllabus is divided into several key areas: Algebra  – equations, inequalities, factorization, and algebraic expressions Geometry  – angles, triangles, circles, and geometric reasoning Measurement  – perimeter, area, volume, time, and conversions Statistics  – data collection, graphs, mean, median, mode Number Theory  – operations, fractions, decimals, percentages, and ratios Vectors and Matrices  – basic operations and applications Relations, Functions, and Graphs  – linear and quadratic functions 📝 Exam Format The exam is made up of three components: Paper 1:  60 multiple choice questions (1 hour 30 minutes) Paper 2:  Structured questions (2 hours 30 minutes) School-Based Assessment (SBA):  A project done in school (for school ca...

 Algebra  🧮  1. Algebra ✳️  Equations An equation shows that two expressions are equal. Example: Solve: 2x+3=112 x +3=11 Solution: Subtract 3: 2x=82 x =8 Divide by 2: x=4 x =4 ✳️  Inequalities Inequalities compare expressions using symbols like >, <, ≥, ≤. Example: Solve: 3x−5<103 x −5<10 Add 5: 3x<153 x <15 Divide by 3: x<5 x <5 ✳️  Factorization This means writing an expression as a product of its factors. Example: Factor: x2+5x+6 x 2+5 x +6 Find two numbers that multiply to 6 and add to 5: (2 and 3) So: (x+2)(x+3)( x +2)( x +3) ✳️  Algebraic Expressions These are combinations of variables, numbers, and operations. Example: Simplify: 3x+2x−53 x +2 x −5 Combine like terms: 5x−55 x −5 📐  2. Geometry ✳️  Angles A straight line = 180° A triangle = 180° A right angle = 90° Example: If one angle in a triangle is 50° and a...
