The Delhi Subordinate Services Selection Board (DSSSB) Post Graduate Teacher (PGT) examination is one of the most sought-after teaching recruitment exams in India. Among the various sections, the Quantitative Aptitude section acts as a game-changer. Scoring high in this section can significantly boost your overall merit, provided you approach it with a strategic mindset. This guide breaks down the top 10 high-weightage topics to help you streamline your preparation.
Data Interpretation is arguably the most critical topic. You can expect 3-5 questions based on tables, bar graphs, or pie charts. The key here is not just calculation but the ability to read data quickly. Focus on ratio, percentage, and average concepts to solve these sets efficiently.
These questions are designed to test your calculation speed. By mastering BODMAS rules and squares/cubes, you can solve these in seconds. Dedicate time daily to mental math exercises to gain an edge.
This is the foundation of mathematics. Topics like divisibility rules, remainders, and HCF/LCM frequently appear in DSSSB PGT papers. Ensure you understand the properties of numbers thoroughly.
These two chapters are the backbone of the entire arithmetic section. They are used extensively in solving Profit & Loss, Simple/Compound Interest, and Mixture problems. If you are strong in these, your speed in other chapters will naturally increase.
This topic often includes problems on trains, boats, and streams. It is a favorite for examiners because it tests your logical reasoning alongside mathematical ability. Practice the relative speed concept to save time during the exam.
Questions on efficiency, man-days, and pipes & cisterns are standard. Learning the 'LCM method' for these problems will allow you to bypass long, traditional algebraic equations.
Expected to appear in almost every shift, these questions test your understanding of cost price, selling price, and markups. Focus on the relationship between these variables to solve complex word problems.
Mensuration requires memorizing formulas for area, perimeter, and volume. While it may seem memory-intensive, the questions are usually direct applications of these formulas. Keep a cheat sheet of shapes like cylinders, cones, and spheres.
These questions often involve calculating interest over different time periods or finding the principal amount. Learn the effective rate method to solve compound interest problems without getting bogged down in complex calculations.
While not as extensive as in some other exams, basic algebraic identities (a+b)^2, (a-b)^2, and their variations are common. A basic grasp of polynomial simplification will secure these marks.
By focusing on these 10 high-weightage areas, you can approach the DSSSB PGT Quantitative Aptitude section with confidence. Stay consistent, practice regularly, and success will surely follow.
