CBSE SYLLABUS 10th Science Practicals
Important Notice:Board has decided to discontinue the practice of providing Blue Print, Sample Question Papers and Marking Schemes in classes IX and X w.e.f. Summative Assessment-II of 2012-13. The weightings in the revised format will be assigned to entire units as mentioned in the curriculum as an alternative of chapter wise weighting given earlier. So students please dont blindly follow.
