cbse board class 10th Board Exam Class 12th

Now it's a time for the Covid-19 pandemic, so several schools have opened to prepare students of class 10th and 12th for the CBSE board exams, and several schools are not opened as they prepared students through online mode. Students are waiting for the official news from CBSE to announce and release the exam date sheet. Once the announcement is made, students can check the class 10th and 12th date sheet on the CBSE's official website. Meanwhile, the central government has repeatedly asked the students of Central Board of Secondary Education (CBSE) class 10th and 12th boards exam 2021 not to pay heed to fake reports on board exams that are being circulated online. Students should regularly visit CBSE's official website to check for the latest updates. The Union Education Minister has already announced that board exams for classes 10th and 12th will be conducted from May 4 to June 10, even though the CBSE is yet to release an examination date-sheet. As concerns of students and teachers over CBSE Class 10th and 12th Board exams 2021 rises, Union Education Minister Ramesh Pokhriyal 'Nishank' this week made several major announcements. Addressing a webinar with students and faculty of the Kendriya Vidyalaya across the country, the Education Minister answered the questions of the students. Pokhriyal's asserted that the exam syllabus will be based on the 2020 Redesigned syllabus, which was changed due to the Covid-19 pandemic. "The students will only have to study the revised syllabus for their CBSE board exams. The questions will only be asked from that portion," he said. Speaking on physical classes and the reopening of schools, he said that that online classes will remain an option for students who are not able to physically join the school. He stated that physical classes will resume and there will be a 50-50 percent balance between online classes and attending classes physically. He added that once it is confirmed that it is safe to ask students to attend schools physically only then a decision will be taken to continue online classes.  As confusion over the syllabus of JEE Main and NEET continues, the Ministry of Education also clarified on the matter. It stated that the syllabus of JEE Main and NEET will remain unchanged for 2021 and continue as that of the previous year. However, unlike previous years, this year the candidates will have options to answer the questions in JEE and NEET examinations. Students will be given the choice to answer 75 questions (25 questions each in Physics, Chemistry & Mathematics) out of 90 questions (30 questions each in Physics, Chemistry & Mathematics). In JEE (Main) 2020, there were 75 questions all of which had to be answered by the candidates (25 questions each in Physics, Chemistry & Mathematics). As per an official release, the exact pattern for NEET (UG) 2021 is yet to be announced. However, in view of the reduction of the syllabus by some boards across the country, the NEET (UG) 2021 question paper will also have options on the lines of JEE (Main).
