On 18th November 2014, CBSE notified additional material on extra sub - topics incorporated in the Class 12th Physics theory syllabus for the March 2015 exam. Students initially go through the new topics that have been introduced in the syllabus. As a matter of fact, since many CBSE schools did not have the access to the content, which was informed in the month of June, CBSE decided to upload the content online. Though the material was informed as part of the syllabus of Central Board of Secondary education, yet many students were oblivious as it was not there in the NCERT textbooks.
The extra sub-topics will be part of the approaching Class 12th board examinations Science students in the chapter on communication systems. The topics comprise internet, mobile telephony & a global positioning system. Vineet Joshi, chairman of Central Board of Secondary Education states that "These are already a part of the syllabus proclaimed before. But we understood that these sub - topics are not there in the set NCERT books. Though we had issued the course content, many schools asked us yet again. We found out that these schools did not get it. So we made a decision to upload them online in the public domain so students & teachers know what to study.”
