syllabus kitna reduce hua ha sir or 2021 12th exam ka kitna percentage mcq ayinga

Asif, you haven't mentioned the exam you are enquiring about and your profile says you are a Science Aspirant. For now only NEET and JEE Mains syllabus have come under discussion. The MHRD did announce that NEET 2021 will be conducted on a reduced and revised syllabus owing to the decreased academic year 2020 due to Corona Pandemic. The department has invited suggestions from the parents. At this point in time, the syllabus hasn't been decided yet. So it is not still unknown what are the topics that might be included and what topics might be omitted. But yes the syllabus will be reduced. So if you are preparing for NEET 2021, stick to NCERT books until the official syllabus has been officially released. But if you have already purchased any books, you can study from them as well because you will get in depth knowledge about each concept. Few topics might not be needed but because we do not know which topics might be reduced and which might not be, we would suggest you to not buy any books atleast until HRD comes with the official syllabus. At this point in time conducting NEET 2020 will be the priority over NEET 2021. So we need to wait. But if this is any other stream except for NEET and JEE, please do let us know and we shall help you with relevant information.
