An ordinary student with a defined strategy, persistent effort and wholesome lifestyle has the ability to obtain a 90% or higher on a 12th board examination – Not only the ‘top’ students!
Understand what 90% in 12th board exams really means
Is it necessary to study for 15 hours straight and memorize the entire textbook just to get a 90% score in a 12th grade exam? The answer is certainly no. It is enough to have a proper understanding of the subject and to practice problem, solving until you become familiar with it. Additionally, you also need to have the skill to briefly and correctly communicate your answer by using proper and accurate statements. The 12th grade examination is mainly a test of your comprehension and ability to present the knowledge, rather than your memorization skills. Your scores will influence your college selection, but your scores do not determine your future level of intelligence or success in life.
Start with a clear study plan and the NCERT
First of all, a good study plan must be drafted which will show the entire CBSE Class 12 subject syllabus and will be compatible with the speed and daily routine. Instead of following blindly a topper’s timetable, make your own plan which will have enough time for study, revision, practice, and rest.
Write down the subjects and chapters and put a sign next to those that are difficult for you so that you can give them more time.
Start with 4, 5 hours of intensive study and gradually, add more time closer to the exam instead of working for 10 hours when you are tired.
NCERT must be your primary book, as most of the questions in the 12th board exams are directly or indirectly taken from the NCERT. Read each chapter thoroughly, solve all the examples and exercises, and understand the reasons for every concept instead of just rushing through the chapters.
Make powerful notes and practise like a topper
Good notes and question practice are the real secrets behind 90% in 12th board exams. Your notes should be short, clear, and written in your own words so they are easy to revise in the last 1–2 weeks.
Keep separate notebooks or sheets for formulas, definitions, reactions, dates, and important diagrams.
Use colour pens, boxes, and flowcharts for topics from Economics, Business Studies, History, and Biology so you remember them better.
Once you finish at least 60–70% of the syllabus, start solving previous year question papers and CBSE sample papers regularly. In the beginning, you can take your time, but later you should solve them in 3-hour exam conditions to train your speed and time management.
After each paper, check your answers thoroughly, find why you lost marks (careless errors, missing keywords, incomplete steps), and write these mistakes so that you don’t repeat them again.
Revise those weak topics in the next 2–3 days so you do not repeat the same mistakes.
Improve answer writing, health, and mindset
To get a 90% score in 12th board exams, you should analyse the manner of your answer writing, not just the content of your knowledge. The CBSE examiners like neat, structured, and step-wise presenting of answers.
In Maths and Science, besides writing the formula, you must show every step and highlight the final answer; thus, you can get some marks even if your answer is not completely correct.
In theory subjects, employ headings, bullet points, underlining, and short paragraphs in such a way that your answers look like they have been written in an organised manner and are easy to check.
If it is necessary, make clear and well, labelled diagrams in pencil, and ensure that your handwriting is neat and readable.
Your brain functions optimally only when your body is in good health and relaxed, therefore, you cannot afford to neglect your sleep, food, and breaks.
Make sure you get 7, 8 hours of sleep daily and try not to study very late at night. Also, eat food prepared at home and ensure that you drink enough water, eat fruits, and nuts.
You must take a 5 or 10 minute break after every 45 or 50 minutes of study. In this time, you should do some stretching, walking, or even closing your eyes instead of phone scrolling.
When you are feeling stressed, you should continue to use basic relaxation methods such as deep breathing, light exercising, or journaling so that your mind stays calm for long, term study.
