Time for my “Tip of the Day”! It’s been quite a while, hasn’t it?

Tips and Hints

Tips and Hints

Well, one thing that I have noticed among my readers, is that many are confused as to how they should study for math and physics. These two subjects leave them desperate for help. Worry not, my friends! Math and physics aren’t necessarily that difficult, if you make an attempt to change the way you look at them. Pretend that those two are your most favorite subjects and which you find very easy, and voila! Slowly and steadily, they will become easier for you.

In the meantime, while you keep your imagination process on, also keep in mind to make notes – in math and in physics. For  math, make notes regarding all important formulae. You will find a PDF on important formule in math below:

The key is to write, write, and write.

Write and rewrite those formulae. Yes, I may sound like a first grade teacher, but that’s the key to memorizing all those formulae! Write them down, stick them on your cupboard or bulletin board, and take five to ten minutes each day to just go through them. You’ll learn them in no time! Half the problem solved! 🙂

Also, practice, practice, and practice those sums. Solve all examples, solve all chapter tests, and solve all exercises. You will then be familiar with all kinds of sums and there won’t be a single question which you won’t be able to solve. Give it a try! Do those examples first and then solve the exercise. The examples are given for a reason – they teach you the basics and all give a variety of sums which you may come across.

The same goes for physics. Write those formulae and rewrite them. Go though them once a day, whether it’s while you brush your teeth, wait for the bus, on the bus ride, during recess, etc. Take a couple minutes out from your day to revise those formulae.

Making notes during class can also help. Writing is what will get you everywhere. The brain finds it easier to store data when you write it. Writing the data helps you visualize it once again and when you look at those formulae, BAM! The data gets stored in your brain. 🙂


Thank you and keep on writing!

How to Study for: Physics

The Electromagnetic Spectrum

A reader requested that I help her with studying physics and I thought I might share it with you all as well. Here is the feedback which I gave her:

For physics, I made notes on small pieces of chart paper. I used index cards – which are approximately 4″x3″ – to take notes of all formulae, conditions, relations between units, quantities and their units, types with examples, uses, important labelled diagrams (such as in total reflection/refraction and lenses), etc. I stuck these index cards on my closet and everyday while brushing my teeth, I would stand in front of my closet and go over those notes. This made it really easy for me to memorize formulae and keep myself in touch with that part of the syllabus which was already over in school. Hence, when exams came, I was familiar with the entire syllabus. Take time out of your day to read through these notes for five to ten minutes. It makes a huge difference!

As per my experience, from the exam point of view, the following is important:

(Note that the following is solely my interpretation of what is important and likely to be asked)


*Relations between units and their derivation

*All derivations mentioned in the scope of syllabus booklet

*Special conditions or characteristics, wherever mentioned

* Examples of turning forces and reasons for the same (They may be asked as 2 mark ‘give reason’ questions)

* Differences

* Factors affecting anything, wherever mentioned

* Factors on which something depends, wherever mentioned

* Special cases, for example in work

* Whether a quantity is a scalar or vector quantity

* Conversions of energy into different forms

* Laws or principles or rules

* Levers in the human body

* All kinds of examples of each class of lever

* M.A. and V.R. of all simple machines and the formulae for the same

* Diagrams with labels

* Critical angle for water and glass

*Absolute refractive index for water and glass

* Minimum angle of delta for which <i = 48 deg

* Numericals related to refractive index

* Applications or consequences or examples, wherever mentioned (May be asked as 2 mark ‘give reason’ questions)

* Diagrams of lenses and their application

* Experimental determination of focal length of convex lens

* Order of electromagnetic spectrum with frequencies/wavelengths

* Properties and uses of electromagnetic spectrum

* Applications of scattering of light

* Applications of echo and resonance

* Wave forms diagrams

* V-I graphs

* Variation of resistance/resistivity with temperature

* Choice of material of wire and why

* Superconductors with examples

* Numericals related to current electricity

* Give reasons, wherever you can find any

* Similarities and dissimilarities

* Ways of increasing magnetic field

* Ways of increasing speed of rotation of coil

* Heat capacity and latent heat examples/applications and reasons for the same

* Heating curves

* Specific heat capacity and latent heat values for ice/water

* Effect of impurities on melting/boiling point

* Properties, wherever mentioned

* Alpha/Beta/Gamma emissions and numericals on the same

I would like to let you know that the aforementioned points are merely what I feel is important and what has been told by my previous teacher as what is asked frequently in the board examinations. Nothing is sure which is why, of course, it is recommended that you study thoroughly. However, you may put extra focus on these points as they will surely fetch you marks in the objective part of the paper, i.e. in Section A.

Thank you!

The following include questions regarding the following chapters of Physics:


Calorimetry Questions

Current Electricity Questions

Electromagnetism Questions

Modern Physics Questions


I was browsing through websites last year, when I was in 10th grade, in search of proper notes and sample questions, hence, I do not remember the website from which I obtained these questions. I would really appreciate it that, if you know the website name, then please do leave a comment, so that I may give proper credit to the same. Alternatively, if you find that the content I’m using is yours and if you wish for me to not use your material, please leave a comment . Thank you! 🙂

The following PDF file, found on the website, contains very helpful notes on the refraction of light. The notes include information on the types of lenses, the images formed when an object is kept at a certain distance from the lens, etc. Do check out these notes! You will definitely find them very useful! 🙂
