ICSE Class 10 Physics Exam 2025: Difficulty Level

Based on initial feedback from students and teachers, the overall difficulty level of the ICSE Class 10 Physics Exam 2025 was moderate to difficult. Here's a breakdown of the paper's difficulty:

Section	Difficulty Level	Remarks
Section A (MCQs & Short Answers)	Moderate	Most of the questions were based on the direct concepts in Physics. Some of the MCQs were tricky but they could be attempted easily with a little conceptual understanding.
Section B (Numericals & Application-Based Questions)	Moderate to Difficult	If the students had a strong grasp of formulas along with correct application of concepts, then it was easy for them to attempt the exam. However, some of the numericals were time-consuming.
Section C (Long-Answer & Diagram-Based Questions)	Difficult	This section consisted of application-based and analytical questions. Questions based on ray diagrams, circuit diagrams, and derivations were tricky.

Some students found the application-based questions in Section B to be lengthy and tricky, while others appreciated the balanced distribution of topics.
