The Central Board of Secondary Education prescribes the CBSE step-wise marking scheme for all subjects. The CBSE board categorises the marking scheme based on various points. Students can earn partial credit for the efforts generally made in writing the formulas, applications and calculations, for subjects like Maths, Physics, Chemistry, etc. For example, if the student doesn’t get the final answer to a particular math question, he/she can still earn partial marks for the correct use of formulas, method, and proper steps in the solution.
Candidates can get partial marks in English, Biology, and Social Science, for major points, relevant facts, examples, etc. Students should not leave the answer blank and must attempt the question and write it accordingly based on their knowledge so they can get some step marks. They can prepare for the board exams by following the CBSE syllabus and marking scheme for all subjects. Read the article to learn more about the CBSE step-wise marking scheme and how it works.
The Central Board conducts CBSE 10th and CBSE 12th examinations for 100 marks. For some subjects, the board categorised 80 marks for theory and 20 marks for practical or internal assessment, while for some subjects, 70 marks for theory and 30 marks for practical work. The CBSE prepares the marking scheme for Class 10 and Class 12 for the evaluation of all subjects in detail. For example, in Mathematics, there are a few steps to solve questions which are considered important. Such steps are value points, and if students mention these points, the marks will be awarded; if not, the marks will not be awarded.
The CBSE board exams are conducted to test the students' knowledge and how much they gained during that particular academic year. If a candidate has secured 33% marks, he/she will be declared as a pass. If the student does not achieve 33% marks or misses out by just 1 mark, the board can decide to award grace marks.
A step-marking scheme is followed in the CBSE board, i.e., even if the student doesn’t attempt the final answer to a math question, he/she can still get some partial marks for using correct formulas, method, and steps, clearly. A student must show the solution steps clearly while attempting the question. If the formula is written and if the candidate attempts the subsequent steps, though there are mistakes in the calculation, he/she could get some credit for their efforts.
Note: Just writing the formula is not enough to get the full marks in maths.
Generally, the Central Board mentions the word-limit for the respective sections. The world limit for all questions in language and optional subjects will be as desired in the question itself. Students can also check their specific curriculum and CBSE exam day guidelines to learn more. For exceeding the word limit, marks will not be deducted; however, marks will not be awarded either.
