If you are preparing for an exam, then revision is an essential process.
Revising many times is the best solution to score well.
But how to efficiently revise is a shadow of a doubt for many.
This article assumes that you are an ardent reader willing to achieve good scores and not just prepared to pass the tests :-).
Revision plays a prominent role in improving the memory of the subject, helps to understand the topic better and also present the matter well in the exam.
Once the syllabus is covered, revision is a mandatory requirement for better scoring in school, college exams.
One need not cover 100% of the syllabus, but he has to revise whatever was read before.
It may even be useless to have covered vast syllabus and going for test or exams without proper revision.
Because all that vast topics you have covered might have leaked out of your memory unless you revised them thoroughly.
Why should one revise?
Revision has certain qualities like
The more number of times you revise the better is your confidence and scoring chances.
♦ You get further clarity, thought, understanding and also interest in the subject by revision.
♦ Revision enhances memory of the issue in terms of formulas, structures (biology, chemistry), diagrams (in biology, physics, geography etc.), steps of derivations (in physics, maths), topic,etc.
♦ It gives you command over the topics which are complex, vaguely or incompletely known to you. Your standards may rise to the extent that you may be able to derive the formula 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 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.
♦ If you think all the attributes mentioned above due to revision are required then one might not ask why revision is necessary.
How to Revise for an exam.
The mode of revision depends on the topic or subject we are about to cover.
Secondly, try to understand the concept besides mugging up. This can be a big mistake for any student in the lifetime if you don’t understand the concept.
English language revision:
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 grip in grammar.
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.
We have a terrible memory for chemical formulas, reactions, the valency of elements, chemical structures, nature of the compounds, etc. in chemistry.
Making mistakes because of the above reasons is always eminent, but a simple mistake changes the meaning of entire reaction. So
During revision view the periodic table and familiarize with it frequently.
Understand the fundamental difference between 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 stereo-chemistry by clarity during revision.
To revise Physics
In Physics we make mistakes in derivations, fundamental units representing force, surface tension, etc., problems & exercise solving. So get 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 hand written 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 end point.
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.
To revise theoretical subjects
Theoretical subjects like biology, medicine, and other social sciences require more of 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.
Biology: 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 animal, 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 the anatomy and physiology.
In Botany: Here you come across different classes of plants which have differences in their life span, seedling or reproduction method, etc. The toughest part comes in biochemistry like photosynthesis, respiration, etc. Here 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.
Revise 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 familiarise the points.
Ex: British was defeated in the American revolution around 1781.
For Maths and Stats revision
Then 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 answer you can find one way on your own and also remember the step better.
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 latter realize the facts about the subject or topic with its related prior knowledge.
Revise as many times as possible the entire subjects.
Try to decrease the time for every revision from the previous revision.
Have fixed time and dates to cover revision part by part.
Once you revise, try to answer a previous question paper, i.e., past papers to see your progress.
Some subjects may not be liked by us but try to accept that they are to be mastered for better scoring.
Use same notes or books or study material for all the revisions because the page of the book also strikes in memory while answering the questions asked.
Last but not least there is no substitute for hard preparation and excitement and enthusiasm in revision.
