hi,

see sastra is considered as one of the best private university. the quality of education and syllabus is up to date, you will be eligible for any of the post bachelors competitive exam. now see gate exam, i.e graduate aptitude test of engineering is different than regular college semester exam, questions difficulty level is quite standard, you have to practice lots of mcq type questions and must have full syllabus in grasp. so apart from college syllabus and studies you have to take separate preparation for gate , follow the previous years papers etc.

hope you understand.
