Learn thoroughly the first time you learn a new concept.
Suppose, the topic Kirchhoff’s laws is taught in class. Revise the topic the same day yourselves. Keep a paper and pen while you revise and jot down whatever you feel important.
- Please note that you cannot memorize derivations by reading. Write and practice the derivations.
Memorizing a derivation is like remembering the path to a new place. There is no need to learn each and every step by rot. Keep in mind the important milestones and curves. You should know where to begin, the important assumptions and considerations which make a twist in the process and the final conclusion. If you find a way like this for each derivation, you will find it easy to remember long derivations.
- While you practice keep a note on the points requiring special attention.
- Try to relate with your daily experiences and objects as an aid to memory.
- Ask doubts. If you have some doubt try to clear it by asking the teacher. Nowadays there are many alternatives also. You can post your doubts at plustwophysics.com and get the answer delivered to your email inbox.
- Use memory maps.
- Try to recall and write the derivations and laws without referring to text.
- Solve numerical problems related to the topic. Do not limit the number of numericals to 2 or 3. Solve as much as you can. For that you may buy a Numerical Problems in Physics book. Mark the difficult ones and ask your teacher for clarification and help.
- Read in advance. Donot wait to read the textbook until it is taught in class. Anticipate the topic to be taught in class and read in advance.
- Don’t use too many reference books. You can have maximum one textbook, one reference book and a numerical problems book. Keep an objective physics if you long for entrance exams.
All the best

Your determination and will power will change the world
A Man Living with Half of a Body..
Peng Shuilin had half of his body amputated after being run over
by a truck. But he never gave up! His recovery has amazed surgeons
after almost two years undergoing a series of operations.
The vice-president of the hospital where this 37-year old Chinese man
has been treated said: He is amazing and the only person in the world
to survive having so much of his body amputated.
The best part of the story is ..
He’s doing well now and has opened his own bargain supermarket
- called the Half Man-Half Price Store.
It seems nothing can get him down
You too can work wonders with your strong determination and the will to win.
“However unlucky you are, whatever mishaps occurred in your life, you will be paid for your hardwork. ”

Just imagine - A school has about 2000 students and each student studies atleast 5 subjects. The student gets on an average (atleast) one page per day as assignment on one subject and this makes 10000 pages per day for assignment/ homework only. If we calculate the total number of students in our country How many trees have to be cut per day to meet this requirement.
I REALIZED this and turned to online submission of projects and assignments.
Let’s Go Green
I have chosen online submission of projects in an attempt to save earth – When assignments are submitted online, paper work is minimised and further storage becomes so easy, it remains in the server and can be referred to any time provided I have access to Internet.
The only hindrance to this is that the students should also take the concept seriously and also the school authorities.
Initially the students find it a little different, but once started they have also started taking interest and they found that they can be more creative while they submit their work, findings, research reports etc as word file or flash presentation or PowerPoint presentation.
I invite all creative teachers to start such an initiative by which you can be innovative as well as we will be contributing to save our mother earth.
http://plustwophysics.com/classroom provides facility for teachers to start courses online and accept projects and assignment online, conduct tests – MCQ, Short Answer Type and Long Answer Type – and grade the assignment – all online. No need for paper work.
There are lots of things you can do to get ready for exams and it’s important to find what works for you. Some ideas of Dos and Don’ts are:
- Have your own revision timetable – start planning well before exams begin. Your teacher should be able to help.
- Make your books, notes and essays user-friendly. Use headings, highlighting and revision cards, and get tips on other revision techniques from teachers and friends with experience of exams. You could also consider buying revision guides.
- Take notes of the important points when revising. Try to answer the questions of past exam papers – explain answers to tricky questions to someone else.
- Everyone revises differently. Find out what routine suits you best – alone or with a friend or parent/carer; early morning or late at night; short, sharp bursts or longer sessions; with music or without noise.
- Ask for help from your teacher/learning mentor, parent/carer or a friend if there are things you don’t understand.
- Don’t leave revision to the last minute.
- Don’t avoid revising subjects you don’t like or find difficult.
- Don’t forget that there is life beyond revision and exams.
- Don’t cram ALL night before an exam – you’ll be really tired in the morning.
Tips for the revision period:
- Leave plenty of time to revise so that you don’t get into a situation of having to do last minute cramming. This approach will help to boost your confidence and reduce any pre-exam stress as you know you have prepared well.
- Develop a timetable so that you can track and monitor your progress. Make sure you allow time for fun and relaxation so that you avoid burning out.
- Make your books, notes and essays more user-friendly with summary notes, headings, sub-headings, highlighting and revision cards. Try using key works or spider charts. Get tips on other revision techniques from teachers and friends – do what works for you.
- As soon as you notice your mind is losing concentration, take a short break. You will then come back to your revision refreshed.
- Experiment with several alternative revision techniques so that revision is more fun and your motivation to study is high.
- Everyone revises differently – find out what routine suits you best – alone or with a friend; morning or late at night; short, sharp bursts or longer revision sessions.
- Take notes of important points when revising as an aid for future revision or if you need to clarify something with a teacher. Try explaining the answers to tricky questions to someone else, or look at past exam papers and try answering some of the questions.
- Don’t drink too much coffee, tea and fizzy drinks; the caffeine will ‘hype’ you and make your thinking less clear. Eat healthily and regularly; your brain will benefit from the nutrients.
- Regular moderate exercise will boost your energy, clear your mind and reduce any feelings of stress.
- Try out some yoga, tai chi or relaxation techniques. They will help to keep you feeling calm and balanced, improve your concentration levels and help you to sleep better.
- Ask for help if there are things you don’t understand. If you are feeling stressed out, talk to someone.
