# WBJEE Mathematics Syllabus

The syllabi for the upcoming WBJEE 2017 exams have been revised recently. The syllabi has been updated to:

i) Avoid any bias towards students any particular school/Board

ii) Leave out more descriptive topics and to give more importance to the analytical ones.

iii) Focus more on the depth of the syllabi rather than the extent of coverage.
