Predicting the Difficulty Level: Insights from 2025
Based on the analysis of the previous year’s paper, the overall difficulty for the Class 10 Maths exam is often rated as moderate.
• Section A (MCQs): Typically considered easy and direct, these questions are heavily grounded in NCERT concepts. However, students should be prepared to solve every question, as these sections may lack purely theoretical inquiries.
• Sections B & C: These sections often require solid conceptual understanding and efficient time management. Some students in the past have found Section C to be particularly “tricky”.
• Sections D & E: These sections contain long-form answers and Case Study questions. While generally manageable, they are often described as lengthy and require strong problem-solving skills.
The Benefit of Internal Choices
To assist students in attempting all required questions, the CBSE provides ample internal choices in Sections B, C, D, and E. In previous years, all questions in Section E (the 2-mark sub-parts of case studies) featured internal choice

• Geometry: Applying properties of tangents to circles, such as the distance between parallel tangents being equal to the diameter.
• Probability: Calculating outcomes for simultaneous coin tosses or rolling two dice.
• Mensuration: Calculating ratios of volumes, such as the volume of a remaining solid after a cone is hollowed out from a cylinder.
