Central Board of Secondary Education (CBSE) is all set to conduct the Class 12 Computer Science 2021-22 Term 1 tomorrow, December 21, 2021. The exam will be held for a duration of 1 hour and 30 minutes, from 11:30 am to 1:00 pm. Since the paper will cover multiple-choice questions, students are expected to identify the right options and mark the same in their answer sheet. Additionally, the paper will also provide internal choices. So effectively, the paper will comprise 55 questions out of which a student needs to cover only 45.
With only a day left for the CBSE Class 12 Computer Science Term I exam, students need to pay close attention to the syllabus and sample papers provided by the central education board.
