Mathematics Optional

  1. How to for prepare mathematics’ optional?
  1. Practice Practice Practice Formula (PPP Formula). 

Practice as much as you can. Take a particular concept of the subject and practice different set of questions of the concept. This will make you concepts clearer and better. For every concept try out different possible solutions through which the question can be solved and rectify every kind of doubt in a particular question.

  1. Try to avoid small and silly mistakes.

Sometimes in exams students are so busy that they tend to commit many silly mistakes. Maths is all about numbers, so while solving questions many students note down wrong figures of the questions which lead to the wrong answer and hence students loose marks in the paper. Try to avoid doing such mistakes in the exam and read every question carefully before giving any kind of answer.

  1. Answers (Solutions) in a proper manner

Many of the students know the answer during the time of exam. But still are not able to score good marks in the exam. This is because they don’t answer the questions in a proper manner due to which marks are deducted. So to score good marks, it’s better to answer each question and present it in a proper manner.

  1. Don’t panic and be relaxed

The best thing to do during preparation is to be relaxed and prepare with peace in mind. Being panic and stressed will not help in scoring good marks. If you prepare with stress and panic then it will hinder your preparation and you may tend to lose marks in the exam.

So it’s better to stay calm and relaxed and preparing without any kind of stress. This will boost your score and result in better marks in the exam.

  1. Go through the entire Maths Optional Syllabus

Before beginning the preparation go through the syllabus well. Understand the syllabus to know what actually is asked in the exams. If you the syllabus well then it gives a clear understanding to you as what could be asked in the exam. also it helps to know which all topics to be studied.

Marks distribution is another aspect about which a student should know well. Through this one can categorise topic which carries the highest weight age and the ones which doesn’t have high weight age. This helps in proper planning for the main exam.

  1. Choose right preparatory books

There are books available in abundance in the market. Theses bulk of books tends to confuse the candidates as which one to opt for better understanding. This creates chaos in the mind of the candidates and results in sheer wastage of time and energy.

So it’s always better to select some books out of many books available in the market and stick to them for the preparation. Clear your concepts and study in depth about a particular topic till the time you become well versed with it. Also don’t solely rely on one book try to explore other books as well if your topic is not cleared by one book. This doesn’t imply to refer 10 books just for one topic. Try to be selective in your choice when it comes to books and study material.

  1. Practice Previous (past) year papers

Practicing past year paper is one of the most vital factors involved in the preparation. If you practice past year papers then you can an idea what exactly has been asked in previous exam. And what are the important topics through which most of the questions arises in the exam. This helps to plan your preparation in a better way and study properly. If you are well versed with previous exam papers then you get an insight what is most important from the exam point of view and accordingly you can solve and practice questions for the final examination

  1. Making Short notes

Most of the books available are too huge and thick that day before the exam a candidate cannot solely study from it. So it’s always better to make notes out of the available books and study materials.

Writing down 1000pages into a short summary of 100pages helps in a quick revision. This exercise of making notes also saves a lot of time and energy. At the end of the notes made by you is something which will help you a lot in exam preparation.

  1.  Time management

Most of the students are unable to manage the time during the exam. This happens because many a times a candidate spends a lot of time in thinking about an answer of particular questions and this leads to a lot of wastage of time. Instead of this one needs to specify and allocate proper time to each and every question.

It will help to finish the paper on time. Also time management is important to avoid any last minute hassle. When less time is left and there are more number of questions left to be answer then many a times a candidate marks a wrong answer even if he/she knows the correct answer.

  1.  Revision of important topics

It is very important to thoroughly study the whole syllabus twice and thrice. And then keep on revising it as many times as possible. Revision helps to absorb the things in a better way. It helps to keep whole of the syllabus in our brain for a longer duration.

If a student keeps on learning and doesn’t revise what he has studied then he tends to forget the thing on the day of the exam. This is because what he/studies didn’t ever got registered in his brain. Thus revision is the key factor to restore things in the brain
