Sample paper for the preparation of the entrance exam…this sample paper contains chemistry and physics questions for the science students…

physics and chemistry are the two most essential subjects for students preparing for competitive exams. A sample paper for these subjects is very helpful for students aspiring for competitive exams as they give a brief idea about the type, number of questions appearing in that exam. moreover it helps them in solving questions and conceptualize the theories which is a revision and practice for them and we all know – practice makes a man perfect! So a must read and solve for students giving competitive exams.

This article contain Competitive exams based questions of engineering and medicine as well.
