We will see how many questions are there, how many marks per chapter and some tips for your board exams.
There are total 4 sections, marks per section and number of questions is given below
|Section||How many marks?||Number of Questions||Total Marks|
|Section A||1 marks each||4||1 × 4 = 4|
|Section B||2 marks each||8||2 × 8 = 16|
|Section C||4 marks each||11||4 × 11 = 44|
|Section D||6 marks each||6||6 × 6 = 36|
Marks per Chapter
According to CBSE Syllabus , the marks per unit is like this
|Unit||Topic||Chapters of NCERT||Marks|
|I.||Relations and Functions||Chapter 1, 2||10|
|II.||Algebra||Chapter 3, 4||13|
|III.||Calculus||Chapter 5, 6, 7, 8, 9||44|
|IV.||Vectors and 3-D Geometry||Chapter 10, 11||17|
|V.||Linear Programming||Chapter 12||6|
In this sample paper, lets see how many questions of which chapter are asked
|Chapter||1 Mark Questions||2 Mark Questions||4 Mark Questions||6 Mark Questions||Total Marks|
|Chapter 1 - Relations and Functions||1||1 OR Question||6|
|Chapter 2 - Inverse Trigonometry||1||4|
|Chapter 3 - Matrices||1||1 OR Question||8|
|Chapter 4 - Determinants||1||1||5|
|Chapter 5 - Continuity and Differentiability||1||1 OR Question||5|
|Chapter 6 - Application of Derivatives||1||1||10|
|Chapter 7 - Integration||2 (in which 1 OR question)||2 (1 Definite Integral, 1 Indefinite Integral)||12|
|Chapter 8 - Application of Integration (Area)||1 OR Question||6|
|Chapter 9 - Differential Equations||1||1||2 (in which 1 OR Question)||11|
|Chapter 10 - Vector Algebra||1 OR Question||1||6|
|Chapter 11 - 3D Geometry||1 OR Question||1||1 OR Question||11|
|Chapter 12 - Linear Programming||1||6|
|Chapter 13 - Probability||2 (in which 1 OR Question)||1||10|
There are total 29 questions, with 1 + 3 + 3 + 3 = 10 OR questions
Observations from the paper
NCERT Questions are very important - 3 Questions out of 30 have come straight from NCERT.
1 Question of 6 marks will come of Linear Programming (Chapter 12)
In linear programming question, correct graph is of 2 marks
1 Question of 6 marks will come of Chapter 8 Areas
In Area question, correct figure has 1 marks
1 Question of 6 or 4 marks will come of Limit as a sum or Definite Integral
1 Question of 6 or 4 marks will come for finding Inverse of Matrix (by Properties of Matrix or Determinant)
1 mark question has no step marking. If answer is wrong, 1 mark is cut.
Chapter 13 Probability Random Variable question or Bayes Theorem Question will come of 4 marks or 6 marks
There is formula to find Area of parallelogram when diagonals are given
- And there is a formula for Determinant of A -1 i..e |A -1 |
Tips for CBSE Boards 2019
Revise the chapters from the Concept wise. Check out the video below
In the exam, start doing the 1 mark, and 2 marks questions first. Then do the questions which you think you can do first.
Example - If you know how to solve Linear Programming Question, do that first.
Keep in mind the step marking in the exam. Don't miss any steps! There are marks for correct figure, and correct formula
Do this year's
Questions from Supplementary Exercise can come. This year's sample paper had a question of 3 vectors coplanar (which is in Supplementary Exercise of Chapter 10 Vector Algebra)
You should know the basic Concept of each topic of all the chapters. This is very important because most question are conceptual. (You can check concepts by clicking a topic in Concept Wise)
- Keep 2 spare pens, pencil and a scale (ruler) in your geometry box
