CBSE Class 12-science Answered
As we know that in 2017, the paper pattern for Maths has been changed.
The sample paper has been released probably to help students understand the change in the paper format since, this year 2 mark questions have been introduced.
In the earlier format, there were only 1, 4 and 6 mark questions.
Following is the paper format with regards to the questions and marks.
The total number of questions increased from 26 to 29.
There will be only 6 long questions this year. 4 mark questions are reduced to 11 from 13.
Ofcourse that is only a sample paper. So, the questions may or may not be the same.
In new pattern, there will be no overall choice in the question paper. However, 30% internal choices will be given in 4 marks and 6 marks questions.
