does questions are repeated from previous years in maths class 12 CBSE boards exam ......
Yes, many questions are repeated from previous years, making it easier to score around 40 marks or more. In examinations, questions are often similar to those from previous years, with slight variations in wording, but the answers remain consistent. In numerical questions, the data may vary or remain the same at times.
In conclusion, practicing with previous year papers can help you achieve a good score in the exam.

There is like 50-50% chances that some questions can be repeated. But you will get to know about the same when you appear in the exam as CBSE doesn't release information about all this. So I would suggest you to practice well and give your best in your exam.
Wish you luck!!!
