Kerala Plus Two Deleted Topics and Focus Areas for Board Exam 2023

deleted portions kerala plus two

The chapters and sections of courses for plus two that would not be included in the final evaluation for the +2 Board examination in 2023 were published by the Kerala State Council of Educational Research and Training (SCERT).

The national school curriculum 2022 has been rationalised by reducing the textbook contents in the national level, but the curriculum subcommittee of Kerala has agreed against changing the curriculum or the texts in the state of Kerala.

However, part of the material won’t be taken into account for the final assessment in order to lessen the strain on pupils during board exams.

The portions of Mathematics, Physics, Chemistry, Biology, Geography, Psychology, History, Political Science, Accountancy, and Business Studies are subject to reduction and revision.
