CBSE 2019 Maths Syllabus 10th 12th Class – Next year, the Central Board of Education is Advised to Run Evaluations. The committee has released an inventory of postsecondary subjects for the assessments which are going to be run in February to March 2019, the date and schedule of the assessments will be published later. Apart from in the 40 different vocational topics, the board will run examinations for Typography and Computer Software (English), Internet programs, Graphics, Office Communication, etc at February as these topics have a bigger practical part, and briefer concept papers.
