To reduce the syllabus-based burden, the Jharkhand Academic Council (JAC) has deleted certain topics from the 12th-class Mathematics syllabus. The JAC 12th Mathematics Deleted Syllabus comes with a vision to simplify the curriculum. It will also promote conceptual understanding of the fundamental topics. Thus, if you are preparing for the JAC 12th Exam 2026 then make sure to follow the fresh syllabus pattern only.

The JAC 12th Deleted Syllabus 2026 will surely help in improving your marks. There were lots of overlapping concepts and unwanted sections. The decision to eliminate such content from the syllabus is beneficial for the students. Now, the new syllabus is convenient to manage. You will get more time for practice as well as revision. The board authorities have aimed at dropping the redundancy in the syllabus. You will also get some extra time to get ready for the competitive exams. Thus, the compact syllabus will prove to be highly advantageous.

This article will inform you about all the central aspects of the JAC 12th Mathematics Deleted Syllabus. Hence, don’t skip the information shared below.

What is the Exact JAC 12th Mathematics Question Paper Pattern 2026?

The JAC 12th Mathematics theory question paper will be of 80 marks. 20 marks are reserved for the practical assessment. Hence, the whole weightage of the Maths paper will be 100 marks. The theory paper will be divided into 2 parts. Part A will carry 30 marks and it will have all objective-type questions (MCQs). Part B will carry subjective-type questions which will be a mix of very short, short, and long-type questions. The weightage of Part B will be 50 marks. You will be given 3 hours and 15 minutes to solve the paper. The table below will help you to understand the JAC 12th Mathematics theory question paper pattern in the right way –

Sections in Part A (Objective Type)	Number of Questions	Marks Allotted
1	Total 30 MCQs	30 x 1 = 30
Total		30 marks
Sections in Part B (Subjective Type)	Number of Questions	Marks Allotted
A	Question numbers 31 to 38 will be very short-answer-type questions (Any 6 questions must be attempted)	6 x 2 = 12
B	Question numbers 39 to 46 will be short-answer-type questions (Any 6 questions must be attempted)	6 x 3 = 18
C	Question numbers 47 to 52 will be long-answer-type questions (Any 4 questions must be attempted)	4 x 5 = 20
Total		50 marks

Part A and Part B Combined		80 marks

What is the JAC 12th Mathematics Topics Weightage 2026?

Once you get an idea about the topic-wise weightage in Mathematics it will become easy to draft the right preparation plan. Have a look at the JAC 12th Mathematics topic-wise weightage.

Topics	Weightage
Relations and functions – types of relations (reflexive, symmetric, equivalence, etc.), types of functions (one-one, onto, etc.), domain, co-domain, inverse of a function, etc.	8%
Algebra – matrices, determinants, matrix operations, adjoint and inverse, applications of matrices and determinants, etc.	10%
Calculus – limits, derivatives, integrals, applications, differential equations, applications of derivatives, continuity and differentiability, etc.	35%
Vectors and three-dimensional geometry – concepts of vectors and scalars, types of vectors, scalar multiplication, angle between two lines, coplanarity of lines, distance of a point from a plane, etc.	14%
Linear programming – linear inequalities, graphical methods of solving LP, maximization and minimization methods, etc.	5%
Probability – independent events, conditional probability, Bayes’ theorem, random variable, probability distribution, etc.	8%
Internal Assessment	20%

You must note that these percentages are the rough values based on the findings of the JAC 12th Mathematics syllabus pattern. If you want to access the most up-to-date knowledge about the weightage or syllabus, visit the designated website of the board at jac.jharkhand.gov.in.
