Takeaways

• 😀 The session is aimed at students who are starting their preparation for competitive exams, particularly focusing on understanding the weightage of topics and types of questions.
• 😀 The syllabus for CBT and CBT 2 exams is largely the same, and the session provides detailed insights into how to approach each topic based on previous exam patterns.
• 😀 The number system is crucial for exams, with topics like composite numbers, rational/irrational numbers, binary numbers, divisibility rules, and more contributing to 1-2 questions each.
• 😀 Simplification, decimal fractions, square roots, and cube roots are important for at least 2-3 questions in the exam, alongside concepts like AP/GP series and percentage-based problems.
• 😀 Average problems, although not explicitly mentioned in the syllabus, are common and often involve percentages or basic arithmetic, contributing 1-2 questions.
• 😀 LCM and HCF-related problems often involve fractions and remainders, and these topics will generate 1-2 questions in the exam.
• 😀 Ratio and proportion topics, including number-based and real-world problems like income and expenditure, are likely to contribute 2-3 questions in the exam.
• 😀 In percentage-related questions, expect topics such as population growth, price variation, and area and volume problems to appear, contributing 2-3 questions.
• 😀 Profit and loss questions are extensive, covering various scenarios like discounts, weight measurement discrepancies, and MRP-based problems. These will contribute 3-4 questions in the exam.
• 😀 Time and work problems, including efficiency-based and alternate working scenarios, are common in exams, and students can expect 2-3 questions on this topic.

Q & A

What is the primary focus of Sahil Sir's session?

The primary focus of Sahil Sir's session is to help students understand the weightage of various topics in competitive exams, such as NTPC, and how to prioritize their study plan effectively.

How many questions can be expected from the Number System topic?

From the Number System topic, students can expect 1-2 questions. This includes topics like composite numbers, prime numbers, rational/irrational numbers, binary systems, and divisibility rules.

What are the key subtopics in the Simplification chapter, and how many questions are expected from it?

The Simplification chapter includes topics such as BODMAS, decimal fractions, square roots, cube roots, and series (AP/GP). Students can expect 2-3 questions from this chapter.

Why is Average considered an important topic despite not being explicitly listed in the syllabus?

Although Average is not explicitly listed in the syllabus, it frequently appears in exams with 1-2 questions. Sahil Sir stresses the importance of preparing for such topics, as they often appear in trick questions.

What are the key question types that can be asked from the Profit and Loss chapter?

From the Profit and Loss chapter, students can expect questions on MRP, dishonest shopkeepers, successive discounts, and weight-based problems. 3-4 questions are typically asked from this chapter.

What topics are included in the Time and Work chapter, and how many questions should students expect?

The Time and Work chapter includes topics such as efficiency, combined work, salary-based problems, pipe and cistern problems, and alternate working. Students can expect 2-3 questions from this chapter.

How does Sahil Sir recommend approaching topics like Time, Speed, and Distance?

Sahil Sir advises focusing on unit conversions, average speed, relative speed, and train-related problems. These topics are crucial, and students can expect 2 questions on this subject.

What is the significance of Mensuration in competitive exams, and which subtopics should students focus on?

Mensuration is significant as it covers area and volume calculations for various shapes (e.g., triangles, squares, circles, and 3D figures). Students should focus on understanding how to calculate the area, perimeter, and volume of these shapes.

What are the expected question types in the Algebra chapter, and what is the number of questions?

The Algebra chapter covers topics such as quadratic equations, identities, and polynomials. Students should expect 2-3 questions from this chapter.

How can students prepare for Probability questions in competitive exams?

For Probability, Sahil Sir recommends focusing on problems related to coins, dice, cards, and random selection from bags. These types of questions appear often, and students can expect at least 1 question from this topic.
