CBSE Class 12 Computer Science Syllabus 2017-18

CBSE Class 12 Computer Science Syllabus 2017-18

Download latest cbse Class 12 Computer Science syllabus for the session 2017-18. Class 12 Computer Science CBSE Board exam will be of 70 marks. 30 marks will be of practicals. In the theory section, chapterwise marks distribution for Python is as follows Object-Oriented Programming with Python- 24 marks, Advanced Programming with Python – 20 marks, Database Management System and SQL – 8 marks, Boolean Algebra – 8 marks & Communication Technologies – 10 marks.

Although the topics and textbooks remain same, the contents vary year by year. Along with Computer Science syllabus for class 12 cbse has also issued the chapter-wise breakup of questions along with weightage of each chapter. That’s why it is recommended to download new Class 12 Computer Science syllabus 2018 this year and be on safe side. We’ve got several queries from students throughout the country regarding their poor performance in the board exams. One noteworthy point was that most of them didn’t bother about the Computer Science syllabus issued by CBSE, they just practised the sample papers or directly appeared in board exams. It’s very important to avoid such situation and practise at least sample papers issued by cbse and previous year questions

Here we have presented the CBSE syllabus for Computer Science class 12 in the same format as released by CBSE, without any changes or editing from our side. Students are advised to download the class 12 cbse Computer Science syllabus for the March 2018 exam even if you have the previous year syllabus because there might be changes in the syllabus, question pattern and weightage of each chapter.
