FOREWORD

Dear Student,

We, at DBGI, are committed to facilitate all aspiring students in their selection of different streams of B.Tech. by putting our efforts in terms of commitment, providing the services of quality and skill oriented education.

The exponential expansion in the field of technology has offered a plethora of job opportunities in emerging sectors. It has also resulted in innumerable demand for qualified “skilled” manpower in these sectors.

At this crossroads of your life where a wrong turn can take you miles away from your goal. Choosing

your career path is an important step because your future is at stake. It is generally observed that a large section of students are unaware of what they want to achieve in their life. This amounts to a

situation like boarding a train without knowing one’s destination. Undoubtedly it may result in waste of precious time and money.

Student Handbook is purposely designed for the students. We have been planning for some time to

provide collective information about academics as well as Institute to our new comers. It comprises complete information of syllabi of all subjects, Lecture Plans, assignments, question bank, tutorials,

marking scheme etc. However in addition to this, if students have any problem or query they can contact Student Information Cell.

We are living in a competitive world; the key to edging out of competition is information and preparation. We hope that this booklet gives you enough leverage to understand about the institute and academics.

Success to a large extent depends on your attitude which includes your sincerity and strong will to

vigorously pursue your goal. It’s your determination to fulfill the requirements that are needed to enable you achieve your goal. It means you have to acquire the required academic qualification and

skills followed by professional qualification and training in your particular field. Once you have these,

you will be able to compete.

With Best Wishes
