CBSE Class 12 Mathematics: Board examiner points out 8 common errors stopping students from getting a full 100
The CBSE Boards 2018 are beginning March 5 and the Class 12 Mathematics exam is scheduled for March 21.
Class 12 Mathematics is a whole different ballgame. Do not expect the paper to be anything compared to Class 10 Boards. However, this is the one paper in which you can most easily score a full 100 marks if you practice well.
India Today Education spoke to Hariyana Vidya Mandir (Kolkata) Mathematics teacher Debjani Kar, an experienced Board Examiner for several years, with almost 20 years of teaching experience, about the common mistakes students make in the Class 12 CBSE Mathematics Board exam for which they lose out on getting a full 100 per cent.
Here are a few tips from the experienced Board Examiner to get full marks on your Class 12 CBSE Mathematics paper:
1.
For the sums of Matrix Elementary Operation, do not change rows and columns together in the same sum. For row transformation, change only row, and for column transformation, change only column.2.
In the Determinant sums, to get full marks, students must use the properties of determinant.3.
For sums of Indefinite Integral, students must write the constant of integration.4.
For Linear Programming problems, proper shading of the feasible region is very important. If the region is unbounded, don't forget to draw the kink line.5.
In the sums of Vector Algebra and 3D-Geometry, do not forget to give vector sign.6.
In 1-mark questions, always try to write the correct answer of the sum. If steps are correct and answer is wrong, step marking or point marking becomes very difficult.7.
Students often forget to write this when solving such problems in their Class 12 CBSE Mathematics paper:
8.
In such questions, remember not to take log on both sides!
