Hello,

In CBSE board, there is no mention of the phrase "double pass mark".

To pass Mathematics in class 11 (or class 12), the student has to secure 33% marks in the final exam conducted by the school (externals in class 12).

This is the only criteria applicable to pass.

Note: For subjects containing practicals, you have to score 33% in that separately.

Hope this helps.

Thanks.
