I am a Class X student in Chennai. In my school I have been told that certain sections of chapters have been deleted for the 2007 Board examinations in Science and Social Science. I am not sure as to what to include and what to omit in my preparation because only certain parts of some chapters have been deleted. Please provide a list of the omitted topics.

You should refer to the Board's document 'Secondary School Curriculum 2007, Volume I' for the exact syllabus. All the content in the NCERT textbook does not form part of the syllabus.
