Ans: You can’t compare like this. Both are on the same level. If you are in class 11th conceptually, then you do have to face problem in class 12th. You will find the class 12th syllabus easier as compare to class 11th. And, entrances exams also contains about 60% weightage from class 11th.

Q.2. How can I score full marks in English 12th?

Ans: Follow these guidelines for scoring maximum marks in English class 12th:
1. Letter-writing and summary writing formats must be in a good manner.
2. Comprehension: Read your comprehension passage thoroughly.
3. Focus on improving your writing skills
4. Solve maximum sample question papers.
5. Prepare notes on character sketches and central themes.
6. Underline important points in your answers.
7. Selective studying is never a good idea.
8. Time management is crucial
9. Handwriting always plays an important role in scoring good marks.
10. It is important to be systematic.

Q.3. How many students appeared in CBSE 12th 2020 science?

Ans: Over 30 Lack Student appeared in the 12th Science Exam, reported by Hindustan Times News Paper.

Q.4. Is CBSE give grace marks in Physics 2020

Ans: There is no such grace marks policy in CBSE although there is a policy of lenient marking if the responses of student say that paper was tough they will mark for the attempted question.

Q. 5. Does CBSE try to pass all students?

Ans: Yes, of course, CBSE tries to pass every student if the students have written well in their exams. But, if the students have not attempted their paper well and up to the mark then CBSE can fail that student. So, to pass in the exams, students should attempt all the questions, also if they don’t know the answer fully.

Q.6. What is passing marks out of 80?

Ans: The passing marks for theory paper out of 80 are 26, out of 70 marks students need to attain 23 marks and out of 60 marks, 19 marks are required to pass the examination. For practical examination, out of 40, 13 marks are required. Out of 30 marks, 9 marks are needed to pass the exam.

Q.7. How is best of 5 calculated in CBSE?

Ans: The rule of best of 5 subjects in CBSE board is to make the average of any 5 subjects in which you have scored highest in your final exam. It is compulsory to take English as one of the 5 subjects and any other 4 highest scoring subjects to calculate the best of five in CBSE.
