    Exams are just knocking at the door…………so all the appearing students must be in tension but tension is not the solution and i think going through whole book line by line at this point of time would not help. As this is time for last minute practice.MORE U PRACTICE AND SOLVE SAMPLE PAPERS MORE U WILL BE CLEAR FROM THE ROOTS.so sample papers are very useful as it holds the whole syllabus.Solving this set of questions can really make your preparation stronger ….
