Top mistakes students make while preparing for CBSE board exams

You must not forget to carry your CBSE board admit card on all exam days. In case you forget, you will not be allowed to write the exam. Along with the hall ticket, students must also carry their pens, pencils, ruler. geometry box etc.

Students need to score at least 33 percent in all subjects. The overall passing marks are 33 percent in CBSE 12th board exams.

CBSE released the CBSE 12th sample papers on the official website- cbseacademic.nic.in. You can download CBSE Class 12 sample question papers from the official website or from this page too. Students must solve and practice the CBSE 12th question papers of previous years' to know the marking scheme, the types of questions asked in the exam, gauge the difficulty level and more. 

It is advised that students solve and practice the CBSE sample papers to ace the board examinations.

To pass CBSE 10th Board exam, students must secure a minimum of 33% marks in each subject including theory and practical/internal assessments. For Theory paper, students must secure atleast 27 marks. For internal assessment, students must secure at least 7 out of 20

To pass the CBSE 12th board exams, students must secure a minimum of 33 per cent in each subject including theory, practicals, and internal assessments. For subjects with practicals, students must pass in both theory and practical separately. Overall students must achieve at least 33 per cent in each subject.

CBSE rarely fails any students who are just one or two marks short of passing. The board employs a grace mark policy. They adjust the marks of students to help them pass the exam.

CBSE 10th marksheet certificate number comprises 7 to 8 digit alphanumeric code. It is labeled as S No or Serial Number. It is used to verify the authenticity of the certificate.

From this year onwards, CBSE has adopted on screen marking 12^th exam. This decision was taken by the examination authority to speed up the process of evaluation. Also, it will help to reduce the totaling error of marks.

You must not forget to carry your CBSE 12th admit card on all exam days. In case you forget, you will not be allowed to write the exam. Along with the CBSE 12th admit card and school ID, students must also carry their pens, pencils, ruler. geometry box etc.

The board releases the CBSE 12th admit card in the first week of February on the official website. Students  need to collect their admit card from their school respectively.  The CBSE 12th exams are held from February until April every year.  

Yes, it is highly likely that you will get about 30-40 % questions from the previous years. I can't say that will be as same as given but the concept will be same. The type of question coming in CBSE board exams is same. The board follows the same pattern.

The previous years question papers will also help you clarify the concepts. 

Students can check and download CBSE Class 12 Chemistry Syllabus by clicking on link. Distribution of marks is as follows:

• Some Basic Concepts of Chemistry - 7 marks
• Structure of Atom - 9 marks
• Classification of Elements and Periodicity in Properties - 6 marks
• Chemical Bonding and Molecular Structure - 7 marks
• Chemical Thermodynamics -9 marks
• Equilibrium - 7 marks
• Redox Reactions- 4 marks
• Organic Chemistry: Some basic Principles and Techniques  - 11 marks
• Hydrocarbons - 10 marks

Once you finish learning with the CBSE 12th syllabus, you can start solving the CBSE Class 12 sample papers and previous year question papers. You can solve the question papers and understand your weaknesses. Thus you can concentrate more on the topics on which you are weak.

Students must ensure to solve atleast one previous year CBSE 12th Mathematics question paper every day to efficiently prepare for the CBSE 12th Mathematics board exam. Make sure to practice the question papers during the last month of the preparation.
