1. Making Notes for Every Chapter
Preparing notes saves a lot of time because you do not have to read the study material and the concepts, again and again, making students tension free and giving their exams calmly.
2. Make Timetable
Following an appropriate study and timetable can help you cover the entire syllabus quickly and efficiently. The Time table allows us to plan time accordingly by giving preference to the subjects accordingly. It also ensures that we don’t miss out on any important chapters before your examinations.
3. Clear Your Doubt as Soon as Possible
Assume you have any doubts about a query or cannot comprehend a topic. You should get immediate advice from a reputable subject teacher to settle your worries in that scenario. Avoid new topics before tests if you have any doubt about them.
4. Study Topics According to Difficulty Level
You should start with the easier chapters and work your way up to the more difficult ones. Studying topics based on their difficulty level will allow you to better organise your time and complete the syllabus in less time. You will have a deeper understanding of all ideas. It increases your confidence, and you have plenty of time to revise it.
5. Attempt Mock Tests
As exam dates approach, students should begin taking practise examinations to better understand their preparations. Students should take practise examinations around exam time to become accustomed to them and do not have time management concerns. Embibe offers free subject-specific mock examinations. They will have a better understanding of the ideas and will be more confident during the tests.
6. Group Study
Students that learn in groups receive fresh information from their peers. Sitting in a group to study might be distracting; yet, a disciplined approach can improve everyone’s learning experience. Furthermore, an interactive learning method makes a tough topic easier to comprehend.
7. Learn with Diagrams
Long chapters can become boring and repetitive for students. So, instead of reading the textbook, draw diagrams to help you understand a specific topic. You can learn a topic more easily this way. You do not need to remember the entire topic; simply memorise the diagram and then expand on it in your language during the exam.
8. Write What You Study
After finishing each chapter/subject/topic, jot down all important points. Maintain a steady pace when taking notes, but don’t let your handwriting suffer as a result. Taking notes while learning will allow you to analyse how much time it takes to understand a topic. It will eventually come in handy during the exam, where you will have to sit and write for hours on end.
9. Exercise/Outdoor Activities
Outdoor physical activity is also necessary for effective retention. Walking, running, jumping, skipping, and biking are all physical activities that stimulate the brain to become more active. According to research, a student’s brain is more active when he walks for 20 minutes than sitting simultaneously. To maintain physiological health, maintain an equal balance of studies and exercise or outdoor activities.
1. First, Read the Question Paper Well
The first step is to try to read and understand your work thoroughly. When writing the responses, you must first comprehend the question and the number of marks. It is necessary to write the solution in this manner.
2. Use the Primary Quarter-hour Effectively
The time limit for reading the question paper is 45 minutes. Use this opportunity to thoroughly read the full question paper. Divide the paper into categories as you read. This will help you obtain a general sense of the questions and build a basic plan.
3. Prioritise Your Attempt
Always start with the easy questions, then go on to the more manageable ones and make sure you finish them before moving on to the more tough ones. This may ensure that you don’t leave any questions unanswered. Once you’ve completed all of the simple and doable questions, your confidence will rise, and you’ll be mentally prepared to tackle the more difficult problems.
4. Don’t Be Concerned About the Tough Ones.
It’s normal to become concerned when you encounter a couple of difficult queries. This is not necessary and can harm your performance. On the surface, they may appear difficult, but once you get started, you’ll find that most of them are a lot easier than they appear. So be grateful for the easy ones and don’t worry too much about the more difficult ones.
5. Ensure Speed and Accuracy.
Use faster computations to ensure that you aren’t dabbling and that your solutions are valid. For example, if you make a mistake in the sign of a term (), you won’t solve quadratic or linear equations questions. As a result, avoiding foolish mistakes is critical to save time. Always follow the tricks we considered in speed strategies.
6. Avoid Thinking an Excessive Amount of a Few Questions
It is necessary to think about the questions before answering them, but not to the point where you waste a lot of time on one question.
You also don’t want to write a long response to a question because it is basic and you understand it. Remember, you just want to respond to the question. Any over-attempt is going to be a mere waste of your time.
7. Select Your Options Wisely
You’ll be given numerous options while answering certain questions; choose wisely. Read the questions carefully before you begin writing your responses. Look inside the question to see what’s being asked.
8. Use Easy Language
The examiner will preferably be impressed by a conceptual answer written in simple rather than one with no conceptual language but written in flowery language.
9. Be Neat and Clean
Your answer should be clear and legible in handwriting. If your answer sheet isn’t clean and handwriting is not clear, it’ll be unfavorable for you.
