SSC CGL/CHSL Quantitative Aptitude & Reasoning Foundation

Build Tier 1 speed and accuracy in Maths and Reasoning with clear methods, short tricks and timed practice

Ghosla Academy · Government Exams Team

This course builds the Quantitative Aptitude and General Intelligence & Reasoning base you need for the SSC CGL and CHSL Tier 1 papers. Every topic starts from the basic idea, moves to a worked example with every step shown, and ends with the short method that saves time in the exam hall. All examples are fresh and written for this course, using Indian contexts like ₹ prices, train journeys and monthly budgets. You will practise with section quizzes, build your own formula sheet and error log, and finish with a timed sectional mock that you analyse for accuracy and speed. Explanations are in simple English with a little Hinglish where it helps. Exam patterns and dates can change with every notification, so the course also shows you how to confirm details on the official SSC website.

What you will be able to do

  • Understand the SSC CGL and CHSL Tier 1 structure and plan attempts around negative marking
  • Solve number system, simplification and percentage questions with fast mental methods
  • Handle ratio, profit and loss, interest, time and work and speed-distance problems step by step
  • Apply core algebra identities, trigonometry values, geometry results and mensuration formulas
  • Read tables, bar graphs and pie charts quickly for data interpretation questions
  • Crack verbal and non-verbal reasoning types such as series, coding, blood relations, directions and syllogism

What you build

  • 30-day arithmetic formula sheet and personal error log
  • Timed 50-question sectional mock with accuracy and time analysis

What you need to start

  • Class 10 level maths (we revise everything from basics)
  • A notebook, pen and a phone or laptop for timed practice
