Dear  Rutik,

Starting this academic year, class IX students will not have internal examinations for languages and social sciences. Similarly, class XI students will have a new paper pattern for chemistry, physics, biology and maths. The pattern has been changed so that students fare better in entrance exams like NEET and JEE . In all the four subjects, around 20% of questions will be ‘difficult’. The changes will affect students appearing for the 2019 exams.

Hope this helps!!
