CBSE published sample question papers for all subject for the year 2012. You can download the CBSE  Sample paper in Physics and the marking scheme for class Xii 2016 here.

Why Practice CBSE Sample Papers and Marking Scheme?

Practising the sample question paper and the Marking Scheme will give you an idea of the type of questions  in the Board Examination 2016. It also gives an insight into “How the value points are allotted marks?” . This helps you to plan well for the exam and get maximum marks by limiting the extend of the answer and get maximum marks and save time.CBSE sample paper

 

The Sample Question Papers submitted by CBSE officially is considered very important. CBSE use to publish a set of sample papers every year which essentially reminds every student the level of preparation expected from each. It was a common practice in every school to grab copies of the sample papers published by CBSE and every teacher used to make sure that all the students compulsorily solve all the questions of the CBSE Sample Papers. Without the CBSE sample papers and previous question papers, many students simply learn by rot a few questions and answers exhibiting a dismal performance in the Board Exam. We don’t you to be a poor performer. Keep it a point that you practise all the questions from the CBSE sample paper.

So, what to do to Download CBSE Sample Paper!
