Class 12 Maths Question Paper Analysis 2024: Students’ Review
We conducted interviews with the students who took the maths exam for class 12 outside to find out their thoughts on the examination. See what students have to say about the Class 12 Maths Question Paper 2024 below:- It was a somewhat difficult question paper. It would range from easy to difficult.
- The document was not too long.
- The paper's severe MCQs and Assertion-Reasoning made Section A the most challenging section.
- Both the MCQs and the Assertion Reasoning were difficult and took a while.
- The questions on very short answers and brief responses were both average. A combination of simple and complex questions was asked.
- Compared to the other sections of the article, the case study was quite simple.
- Application-based questions (case study/assertion reasoning) were included in the paper.
- Nothing that wasn't covered in the syllabus was asked.
- The format of the sample paper and the marking scheme were followed by the question paper.
Class 12 Maths Paper Analysis 2024: Experts’ Review
We spoke with a few teachers who are subject matter experts after the exam to get their opinions on the maths question paper.- There's a good balance between simple and complex questions in MCQs.
- Comparatively speaking, the case study was simpler than the other assignments.
- The format of the sample paper served as the sole model for the question paper.
- Student scores are raised in the middle sections. When faced with application-based issues, students must use logic, apply formulas, and find relevant solutions.
