CBSE Class 12 Maths Sample Question Paper 2023: With the release of Class 12 Mathematics Sample Paper 2022-23 (code 041) by CBSE on their official website, it’s now time for the students of Class 12 Mathematics to start preparing for their exams.
“The only way to learn mathematics is to do mathematics.” – Paul Halmos
In other words, the only way to prepare for a Mathematics exam is by doing Mathematics i.e, practising the different questions. You do not have to worry and fall in the downward spiral of finding the right book and guide books. All you require is the prescribed texts by the board.
- Mathematics Part I - Textbook for Class XII, NCERT Publication
- Mathematics Part II - Textbook for Class XII, NCERT Publication
- Mathematics Exemplar Problem for Class XII, Published by NCERT
- Mathematics Lab Manual class XII, published by NCERT
In addition you can make use of previous year papers as well. Besides, now that the board has made available the latest sample papers, utilising these sample papers for 2022-23 and the marking scheme, students must practise the different kinds of questions that can be asked in the CBSE class 12 Mathematics board exams.
If you are lacking any of these resources, Jagran Josh has the latest CBSE class 12 Mathematics syllabus, and the latest sample paper and marking scheme in one place.
