Teachers have just one advice for students of the science stream who are set to take the board exams — write precise answers, and pay attention to the mathematical and analytical aspects such as numericals and graphical representations.
Students have three days after the English exam to make the final preparations for their Physics paper. It is strongly recommended that students focus carefully on the distribution of marks across various topics.
Optics (Ray diagram, telescope, microscope, Lens maker’s formula) – 14 marks
Electrostatics, Magnetic Effect of Current and Magnetism- 8 marks each.
Electromagnetic induction and AC circuits - 8 marks and 7 marks, respectively.
Electronic Devices - 7 marks
Atoms and nuclei - 6 marks
Dual nature – 4
Communication – 5
“Other than solving sample papers to test their time management skills, students must go through the working of the devices, numericals and derivations. Numericals should not be left out, since there are marks even for steps,” said Pramada Lele, who teaches Physics at Springdales School (Pusa Road).
For this subject, presentation is as important as the subject matter. Students should now start going through the SI units of all entities and the various formulae. Attention must also be paid to the distribution of marks for the topics.
P-block elements – 8 marks
Aldehydes, Ketons and Carboxylic Acids – 6 marks
Solutions, Electrochemistry and Chemical Kinetics each for 5 marks
D and F block elements for 5 marks
Haloalkanes and Haloarenes- 4 marks.
While taking the exam, students must remember to write all descriptive answers in points and provide graphical representation wherever possible to enhance visibility. It is also important for students to go through the paper once before answering the questions. They should also give precise answers to all short answer questions.
Students taking the biology exam have one challenge to surmount - little preparation time before the main exam. With just three days between the chemistry (March 13) and the biology exam (March 17), students must divide time in a way that will see them through their entire syllabus.
While students can focus on some important topics such as reproduction, genetics and evolution, biology and human welfare and ecology and environment, it is advisable for students to go through the distribution provided by the CBSE Board.
Genetics and evolution – 18 marks
Reproduction – 14 marks
Biology and human welfare – 14 marks
Ecology and environment – 14 marks
Biotechnology and its applications – 10 marks
“Students must be thorough with the units they have already prepared. Since there are just two days before the biology exam, students must take two days after the physics exam (March 5) to completely go over the biology syllabus,” said Mala Gupta, who teaches biology to Class 12.
Scheduled for March 26, students will have just one day after the Mathematics exam on March 24 to prepare for this computer science. It is, however, not entirely unachievable. Teachers say that students need to focus on the distribution of marks among various topics.
C++ programming – 35 marks
Introduction to C++-15 marks
Computer fundamentals and programming methodology – 10 marks each
Before students start writing, they must take the first 15 minutes to go through the paper. They should also try to substantiate answers with a small programme to enhance clarity.
