How to Revise | 10 Essential Tips for English, Science & Mathematics

If you are preparing for an exam, then revision is an essential process. If you wish to revise

  1. Decide the exact syllabus to be covered
  2. Collect required books and study material
  3. Make a Plan to complete the syllabus.
  4. Plans for revisions
  5. Have a team of colleagues if needed.

Revising the syllabus as many times as possible is the best solution to score well in exams.

This article assumes that you are an ardent reader willing to achieve good scores and not just prepared to pass the tests.

I believe it is useless to cover vast amount of syllabus and go for exams without proper revision.

Because all that vast topics you have covered might have leaked out of your memory unless you revised them thoroughly.

One need not cover 100% of the syllabus, but he has to revise whatever he has read before.

This process helps to improve the memory of the subject, understand the topic better and also presents the matter well in the exam.

Why should one revise?

One should revise because it

♦ Helps to enhance your confidence of better scoring.

♦ You get clarity and generates interest in the subject by revision.How to Revise

♦ Revision enhances the memory of the formulas, structures (biology, chemistry), diagrams (in biology, physics, geography, etc.), steps of derivations (in physics, maths), topic, etc.

♦ It gives you command over complex topics to rise your standards. You will be able to derive the formulas you forgot just before answering.

♦ Revision increases the rate of problem-solving. i.e., your ability to answer the number of problems of physics, maths, chemistry, etc. in a limited amount of time. This helps you buy time to answer more questions in the given time and also think of ways to solve unanswerable questions.

How to Revise for an exam.

This varies based on the subject we are about to cover.

However, there are few common traits for all the subjects like

1. One should understand the concept well besides mugging up.

If you do not understand, it does not generate interest and you will not be able to use it for future practical purposes.

2. Have enthusiasm as it helps work hard for preparation with revision.

3. Use the same note book or study material for all the revisions. Because, even the page of the book also strikes in memory while answering the questions.

4. Have fixed time and dates to cover revision part by part.

5. Revise as many times as possible the entire subjects.

6. Try to decrease the time for every revision from the previous revision.

7. Once you revise, try to answer a previous question paper, i.e., past papers to see your progress.

8. We may not like some subjects, but we need to accept that they are to be mastered for better scoring.

For the English language

Mistakes occur in grammar, so you need to be clear of the basics like the noun, verbs, adjectives, and where and what participles to be used, etc.

You need to solve many exercises to get habituation and also a grip on grammar. You can try Grammarly software in case.

If you need to write an essay, you need to read the main components and actual meaning of the story to put it in your own words and ideas when asked.

Or if you need to write an essay on any current political topic or so then, you need to frame your ideas around the topic and present it with an introduction to the subject followed by an elaborate body with past and present happenings as you do in persuasive topics. Try to give an optimistic conclusion.

It’s even better to use the grammar you study in your daily English while speaking to others.

For Chemistry

Chemistry relies on chemical formulae, structure of molecules, reactions, properties of compound etc.

We have a terrible memory so making mistakes is possible. But a simple mistake changes the whole meaning of the entire reaction.

So we need to register the structures in mind. For this we used to stick the paper containing strcrure and reactions on the wall to revise them frequently.

During revision you can view the periodic table and familiarize it frequently.

Understand the fundamental difference between basic terminology like atomic weight, atomic number, element, compound, acid, base, salt, isotopes, isobars, etc.

Practice the reactions involving using combinations. Refer to the chemical reactions having isotopes emission particles etc. in nuclear chemistry.

Familiarize the stoichiometry principles of equalization, clarify the differences of the first order, second order, exothermic, endothermic and other types of writing the reactions.

Be thorough in the valency of organic and inorganic elements; it helps you make no mistakes in the representation of reactions. Even write them on your own during revision to see for possible errors.

Solve the problems and exercises after revising the formulas and even practice derivations and structures of stereochemistry by clarity during revision.

For Physics

In Physics we make mistakes in derivations, fundamental units representing force, surface tension, etc., problems & exercise solving. So one should be thorough with them

In objective type competitive exams, we mess up with finding the right way to solve and using a suitable formula to get the answer. This drastically consumes valuable time leading to less scoring.

So during revision, better have your handwritten class notes for all the derivations and problems.

Try to familiarize the derivation based on diagrammatic representation and also the way of the flow of steps to the endpoint.

This diagrammatic picture or view helps you recall the answer well and drawing them in the exam enhances your score. Ex: Geostationary satellite velocity- which can be easily derived with proper drawing & understanding instead of mug up.

Revise and learn physics with a better understanding and getting clarity on the topic makes you a master in it.

During revision for objective type, tests try to answer the problems or exercises by visualization and the possible reasoning to solve it. Memorizing the formulas can give ways for solving these problems as you feel.

For theoretical subjects

Theoretical subjects like biology, medicine, and other social sciences require more memorization besides understanding. So

Try to revise the topic using a diagram or picture concerned so that you remember the topic well in connection with it.


Revision is of prime importance in biology branches like zoology, botany, biochemistry, microbiology you have varied topics. But in general topics like cell biology, cell metabolism, cell function, etc. are similar in all the branches. So being thorough in these helps you revise these topics for other branches.

In Zoology

You may face problems in different classes of animals, their sub-divisions like mammals, reptiles, Aves (birds), fishes, amphibians, reptiles, insects, etc. They have differences in the organ system, tissues, arrangement, mechanisms of physiology, metabolisms, So you may need to be clear with these concepts paying particular emphasis. Even vertebrates and non-vertebrates differences need to be clear. Even the practice of diagrams helps you memorize anatomy and physiology.

In Botany

Here you come across different classes of plants that have differences in their life span, seedling or reproduction method, etc. The toughest part comes in biochemistry like photosynthesis, respiration, etc. Here, the advice is to try to understand the complex chemical changes happening by discussing with your friends. It will be not only surprising but also exciting to know how plants survive. Then practice the steps in Krebs cycles (carbohydrates pathway) and other cycles in their biochemistry. If not you may not be able to answer without mistakes.

Revisit the scientific and medical terminology along with its meaning as this can enhance memory of the term. Familiarize with concerned scientists’ names.

In Science, many terms are of Greek or Latin in origin 🙂

Try to learn with some clues and image visualization. (EX; In SYNERGY- ‘syn’ means together & ‘erg’ means energy).

Practice the diagrams as you may need to draw, label and explain while answering. The pictures help to enhance the scores or marks awarded for the answer.

In Sociology, Psychology, Economics, History, Law, religion, etc.

These subjects require mug up of the topics but trying to link them to some situations, persons, behavior, places, etc. makes them remember and explain them quickly during the exam.

If the subject is of Law, history, arts, etc. then try to have some signs or symbols sort to remember the dates of history and rules of the law. And try to discuss the topics among your friends and groups to familiarize the points.

Ex: British was defeated in the American revolution around 1781.

For Maths and Stats

The best way as everyone says, practice-practice-practice. But tips to consider

Formulas; Make a note of them on a plain paper and fix them before your bed or sort 🙂 to view them frequently and memorize them. Because if you remember the formulas possibly, the problem solving is half done.

In mathematical problems, you need to understand the flow of steps towards the answer but not mug-up the steps. Because if you forget even a single step, you may stop solving it. If you try to flow steps towards the answer you can find one way on your own and also remember the step better.How to Revise

Try even answering new problems from question banks, past papers, etc.

Stats calculation is time-consuming in spite of the use of calculators so answer others before statistical problems.

This method not only builds your confidence but also trains your mind to solve the problems faster.

Techniques to revise effectively

Understand the concept! And don’t just mug. This mugging up is a big mistake made by many schools going students till the mental maturity. Understanding the concept shows you the real sweetness of the subject and makes you perceive even more of the subject with enthusiasm.

The difference between mugging and understanding is that mugging is a memorizing aspect while the latter aims to realize the facts about the subject with its related prior knowledge.
