MBSE Class 12th 2022 Exam Preparation Tips
Students in Class 12 can pass with good grades if they practice learning and grasping things in a simple and effective manner. Because the syllabus is so extensive, it is critical to schedule your studies ahead of time.
Here are some pointers for getting good grades in Class 12 at the Mizoram Board Examinations.
A detailed strategy and study plan are required to achieve better results in any examination.
You should be aware of your own strengths and weaknesses and tailor your own preparation accordingly.
Maintain a positive outlook and begin your studies as soon as possible.
Try to write and practice the majority of the chapters yourself, including the computations. For example, problems based on computations may appear in several Mathematics chapters. Therefore, it is preferable to practice and solve them on paper by yourself.
If you are finding any difficulty while studying for the Class 12 syllabus, we at Embibe are here to help you. We have developed several study tools and practice sessions for the Class 12 syllabus.
Keep a well-disciplined timetable so that you can study every day in an orderly manner.
Spend a little more time on the subjects and topics you feel are difficult.
If there is any confusion, ask all doubts to your teachers or elders, or you can use the Embibe tools. They can answer all of your questions.
Try to study every day to finish all the topics prior to the examination.
First, revise the concept studied the previous day before starting with any fresh topic.
Know the chapter weightage of each subject.
Refer to the textbooks and question banks.
Exam Taking Strategy
Giving your best in the examination is as important as the preparation process. You might have completed the preparation of all subjects with proper understanding, revision, and mock tests. This is not enough. To score well in the exam, it is very crucial to answer all the questions in a very detailed manner within the prescribed time limit.
Before starting the preparation, know the question pattern clearly.
Know your weak and strong areas in the syllabus. It will help to prepare a good exam revision timetable.
Don’t forget to make notes during the exam preparation.
Take frequent mock tests to improve your presentation of answers and time management.
Work through at least 5 years’ previous question papers.
Take a small break after studying for an hour.
Don’t study anything new just before the examination.
Carry a proper admit card to the exam centre.
First, fill the OMR Answer sheet and question booklet with mandatory details like name, registration number, question paper series, and centre code, without any mistake within the first 15 minutes.
Use only a blue or black ballpoint pen for making entries in the question booklet and the answer sheet/booklet.
Don’t make use of any whitener or correction fluid for making changes in the entries or answers on the answer sheet and question booklet.
Don’t leave the exam allotted seat until the duration of the examination gets over.
Before starting entries on the question booklet and the answer booklet, read the instructions printed.
Take all necessary stationery items to the exam hall without fail.
Don’t waste too much time on reading and answering the questions whose answer you’re not sure about.
Don’t forget to give the question number correctly in the answer sheets.
Don’t leave any questions unanswered. Just try to attempt the question and at least put the question number in the answer sheet.
Listen to all the instructions provided by the invigilator during the time of examination.
Before giving the answer sheets to the invigilator, make sure you have attempted all the questions and the numbering of each question is done in the correct order.
Don’t get too stressed, and as said, always keep a positive attitude.
Detailed Study plan
Here is a detailed study plan on how to approach each exam and students can go through the general points and subject-wise exam strategy for better scores:
A detailed study plan is a well-structured plan created by students listing their learning goals and study time.
Prepare subject-wise and day-wise timetables.
Spend four to five hours each day by yourself in studies in a well-planned manner.
If you are studying mathematics, accountancy, and physics, you definitely need a pen and paper to write and practice.
While studying every subject, connect them to real-life situations. This will help you to remember every concept in an easier manner.
Embibe has created interesting videos and practice sessions on all Class 12 topics, and if you need a better understanding of all the concepts, you can use them.
Mock tests are a must before the final exam.
Study strategy for Mathematics:
For many pupils, Mathematics can be difficult to learn. The following are some mathematics strategies to improve your understanding.
Develop a deep understanding of the concepts and important topics to increase your grades.
Practice solved problems and exercise questions daily.
Study easy concepts first, followed by the difficult ones.
During practice sessions, avoid making silly mistakes and make an effort to correct them.
Make a list of important equations in a book and revise it regularly.
Make use of short methods in the calculation to save your time during the exam.
Know the Blueprint and question pattern thoroughly.
Solve previous year’s question papers.
Study strategy for Chemistry:
Due to the numerous equations, reactions, formulas, and experiments required in Chemistry, it can be a complex subject at times. To get good grades in Chemistry, you can follow the recommendations below:
Students must do a thorough study of the subject and put in a lot of practice time.
Understand the basics before proceeding on to the more difficult topics.
Important formulas and equations should be written down on a piece of paper or a chart that you can view every day. If you do this, you will be able to recall them clearly during exams.
Utilise the laboratory on a regular basis. It will help to gain practical knowledge and a better understanding of the basics.
Understand the blueprint as well as the question pattern.
Solve at least the last 5-years’ question papers.
Study strategy for Physics:
Few students consider Physics a difficult subject because of several numericals, experiments, formulas, Laws, and diagrams. Students can overcome these issues by practising the following methods.
You should gain a thorough understanding of the fundamental principles first.
Understand the relationship between various concepts.
Physics exams frequently include questions that include theorems and formulas. Hence, focus on it more.
Write and solve numerical problems with a pen and paper to learn Physics.
Have a clear idea of the blueprint and old question paper.
Make a list of important formulas, laws, and diagrams.
Take frequent mock tests.
Study strategy for Biology:
Biology is a simple, interesting subject related to the living organism and its surroundings. It is a scoring subject. Here are some strategies to improve your grade.
Practice drawing a neat labelled diagram.
Make a list of important topics like scientific names of plants and animals, diseases, causative organisms, and symptoms.
Avoid spelling mistakes as it has many technical words.
Do not spend too much time on diagrams.
It is a good strategy to give priority to the important chapters and topics to make exam preparation simple, stressless, effective, and time-saving. Here is the list of some important chapters from each subject of Class 12.
