ISCE Physics Exam

The Physics exam is just a few days away. Hopefully you have read my earlier article on preparing for the Physics exam. I am sure you have revised the entire syllabus and especially these important topics given below:

Ampere circuital law: applications
Applications of Kirchoff’s Laws
Derivation of Lensmaker’s Formula
Energy Level Diagram of Hydrogen Atom
Gauss Theorem
Interference of Light
Nuclear Fusion
Numerical examples on combination of cells
Numerical Problems based on alternating current
Numerical problems on prism and Lens maker’s formulae.
Phasor diagrams, for LR, CR and LCR circuit
Power Factor
Ray diagrams of optical instruments
Resolving Power of Telescope
Sign Convention in Lenses
Sign conventions in Lenses and Mirrors
Zener Diode

Some of the “easy” topics that you should NOT out leave out are: semiconductors, logic gates, EM spectrum, definition of modulation and demodulation, block diagram of a communication system, working of an optical fibre, nuclear physics, properties of alpha, beta and gamma rays, nuclear reaction equations (what happens when an alpha / beta / gamma particle is emitted?), Bohr’s orbits.

Use the next few days to revise what you have already studied throughout the year. Don’t ignore numerical problems in physics.


  1. Every derivation will have a diagram. Draw that diagram in pencil and label the diagram. That way you can save time in describing the diagram again in words.
  2. Check carefully what is the end-point of the derivation. What is the final equation required – that is important. Put that final equation in a box to highlight it.
  3. Attempt all numerical examples. Write the equation that you will use to solve the problem. A simple diagram can be very helpful in solving a problem. Express the final answer with proper units.
  4. Write your answer to the point. Remember, every question has a certain time allotted for it. If you spend too much time answering a question, you will be robbing another question of its time and will not be able to complete the paper.
  5. You are not yet a Doctor 🙂 (Although I know some doctors have the most beautiful handwriting, its generally true that a doctor’s handwriting is difficult to read). Your handwriting should be legible. Write your paper neatly. A human teacher will read your paper and if she does not understand what you have written, how do you expect to get marks?
  6. Avoid cancellations. Avoid overwriting. In case you have made a mistake in writing something, don’t overwrite. Instead, cancel that with two parallel lines drawn across and rewrite on the next line.
  7. Complete your answer in one place. If a question has parts (A), (B), (C) and (D), answer all the parts one after the other and then start the next question. Dont solve in a sequence like this : 1A, 1B, 2C, 2A, 3D….Its messy for you and for the examiner, more so for you. You will not be able to keep track of which parts you have answered.
  8. Pay attention to any instructions given by the Supervisor. Sometimes last-minute instructions are given and those are crucial.
  9. Don’t borrow / lend your stationary from/to your friends in exam hall. You will save time that way and avoid any misunderstanding with the supervisor.

All the best for the exams and for your career.
