Hi Sairam,
                      The competition for the entrance examination for the engineering colleges is very tough as the number of aspirants is very high. Almost all the entrance examinations have the elements of Mathematics, Physics and Chemistry of the 10+2 level examination. It is, therefore, imperative that the candidates prepare thoroughly in these subjects. Some of the entrance examinations are descriptive type whereas others are objective type. Hence the candidates must master both the methods by regular studies and constant practice. There is no substitute to acquiring more knowledge by hard work. If the candidates get hold of previous years question papers, it would certainly help them in preparing methodically and thoroughly. It is also advised that the candidates appear in as many entrance examination as possible. It would not only make them study hard, but will also provide more chances of success.
