ODISHA BOARD CLASS 11 EXAM

A Council for Higher Secondary Education in Odisha was established under the Odisha Higher Secondary Education Act 1982 to oversee, control and develop Higher Secondary Education in Orissa. Odisha board prepares the curriculum and syllabus for Class 11 students and is also responsible for conducting the Class 11 exam. 

Class 11 subjects are important for students since they lay the foundation for Class 12 exams as well as degree-level exams. Essentially, the board aims to instill critical thinking, open-mindedness, and flexibility in students’ learning. As a result, the board provides Class 11 students with high-quality education and skills. Read this article to learn more. 

Exam Summary for Odisha Board Class 11

For each stream, the exam consists of 9 subjects. Five subjects are compulsory for students of all streams. Each of these subjects, namely English, Main Indian Language (MIL), Environmental Education (EE), Yoga, and Basic Computer Education (BCE), carry 100 marks each (1st year-Theory-70 marks and 2nd year – project/practical 30 marks). Apart from these, there will be 4 elective subjects.

BSE Odisha Class 11 Preparation Tips for Physics

Physics has certain central theories and principles and other theories that are based on these central theories. So, the BSE Odisha Class 11 Physics syllabus must be completely covered. Otherwise, it will be difficult to understand concepts in the Class 12 Physics syllabus that will be studied later.

1. Read the Class 11 NCERT textbook of Physics thoroughly. Understand the chapters properly.
2. Remember to visualise the various mechanisms, processes, experiments, etc. This is very important when it comes to Physics.
3. Note down the important points for every chapter in a separate notebook – definitions, short descriptions, formulas, diagrams, equations, etc.
4. Please take a look at the steps to solve problems from the example problems.
5. Solve practice questions at the end of the chapter. Mark difficult questions to revise/practice later.

BSE Odisha Class 11 Preparation Tips for Chemistry

There are three parts to the BSE Odisha Class 11 Chemistry syllabus – Physical Chemistry. Inorganic Chemistry, and Organic Chemistry. Physical and Inorganic Chemistry is comparatively easier than Organic Chemistry, which involves a lot of chemical reactions.

1. Like Physics, for Chemistry, too refer the NCERT Class 11 textbook. Understand every concept, topic, mechanism, process, reaction, etc.
2. Chemistry needs one to remember a lot of formulas, reactions, equations, etc. So, jot down the equations, reactions, and formulas while studying.
3. Write down the definitions of various terms, short descriptions of various processes, reactions, experiments, etc.
4. Practice the reactions and equations regularly.
5. Get an idea about how to solve problems from the example problems.
6. Solve questions at the end of the chapter.
7. Revise the theory, equations, reactions, and formulas regularly.

BSE Odisha Class 11 Preparation Tips for Mathematics

Mathematics is an important subject for engineering aspirants. This subject needs one to remember a lot of formulas. However, remembering the formulas without understanding the theory behind them is not at all recommended.

1. Refer to the NCERT books and understand the theory behind every concept and topic.
2. Jot down the formulas for a chapter: understand them and practice their derivations.
3. Remember the formulas by heart.
4. Go through the solved problems to understand the steps to solve problems.
5. Solve the questions at the end of the chapter. Also, with practice, students will discover and learn the various shortcuts and tricks required to solve problems.

BSE Odisha Class 11 Preparation Tips for Biology

Biology is important for medical aspirants. It is a theory-based subject, and one needs to remember many diagrams, processes, scientific names, etc.

1. Read the various concepts in detail from the NCERT Class 11 Biology book.
2. Write down the important terms, points, short descriptions, diagrams, flow charts, scientific names, etc. to go through them regularly.
3. After finishing a chapter, solve questions. Then, revise them regularly, both theory and the questions.

Important Points for BSE Odisha Class 11 Preparation

During the BSE Odisha Class 11 preparation, remember the following points:

• The class 11 final exam will mostly have theories and fewer numerical questions. So, students have to prepare for that as well. Make notes of various definitions, short descriptions, experiments, etc. Refer to previous year papers to get an idea about what kind of theoretical questions are usually asked.
• Solve numerical problems for every subject diligently. However, in entrance exams like JEE and NEET, a candidate can mostly expect numerical questions or application-based questions, i.e., by applying knowledge ask.

 

Detailed Study Plan

The difference in the difficulty level between 10 and 11th is very wide. Several new chapters, concepts, and topics are added to the class 11 syllabus. Moreover, every concept and topic is explained in much more detail. This means students must have a deeper knowledge to score well. Furthermore, class 11 needs a more vast and thorough knowledge of theories, formulas, visualisations, etc. Additionally, questions asked in the class 11 exams are not as direct as in the class 10 exam. Candidates must be prepared for indirect questions. Let us now look at a detailed preparation plan for BSE Odisha Class 11 specifically for PCMB subjects.

The most commonly asked questions in Odisha Board class11 are given below:

Q.1: What is the difference between CBSE and BSE Odisha?

Ans: CBSE refers to the Central Board of Secondary Education, which is a national level board of education in India for public and private schools controlled and managed by the Union Government of India. On the other hand, BSE Odisha refers to the Council of Higher Secondary Education, a board of education imparting senior higher secondary education for public and private schools and colleges under the State Government of Odisha, India.

Q.2: How many compulsory subjects are there in the Class 11 Odisha syllabus?

Ans: 5 subjects are compulsory for students of all streams. Each of these subjects, namely, English, Main Indian Language (MIL), Environmental Education (EE), Yoga, and Basic Computer Education (BCE), carry 100 marks each (1st year-Theory-70 marks and 2nd year – project/practical 30 marks).

Q.3: What are the elective subjects in the Science stream in Odisha board Class 11?

Ans: The compulsory electives for the science stream students are: Physics and Chemistry. Moreover, a student must study any four Elective Subjects out of the following groups as 3rd and 4th electives. Candidates must select their 3rd and 4th elective subject from Group – A and their 4th Elective from Group B. 

Group – A: Mathematics / Biology / Geology (can be opted as either 3rd or 4th elective subject)

Group-B: Electronics/ Statistics/ Geography/Computer Science/ Information Technology/ Biotechnology/ Economics/ Sanskrit (can be opted as 4th Elective Subject only).

Q.4: How to study for the Class 11 Science stream?

Ans:Read the various concepts in detail from the BSE Odisha Class 11 books of Physics, Chemistry, and or Biology. Note the important terms, points, short descriptions, diagrams, flow charts, scientific names, etc. Revise them regularly to remember them in the long term. After finishing a chapter, solve questions relevant to the section and practice the mock tests available on Embibe.

Q.5: What are the common topics in Physics between the BSE Odisha syllabus and JEE Mains syllabus?

Ans: The common topics in Physics for BSE Odisha Board and JEE Mains are Properties of Matter and Fluid Mechanics, Electrostatics, Semiconductors and Communication System, Electromagnetic Induction and Alternating Current, Ray Optics, Magnetic Effects of Current, Laws of Thermodynamics, Current Electricity.

The future exam for Odisha Board class 11 is Odisha Board Class 12 exam (Check outOdisha Board Class 12 Time Table here).
