FOREWORD

Dear Student,

We, at DBGI, are committed to facilitate all aspiring students in their selection ofdifferent streams of Batch. By putting our efforts in terms of commitment, providingthe services of quality and skill oriented education.

The exponential expansion in the field of technology has offered a plethora of jobopportunities in emerging sectors. It has also resulted in innumerable demand forqualified skilled manpower in these sectors.

At this crossroads of your life where a wrong turn can take you miles away fromyour 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 ofwhat they want to achieve in their life. This amounts to a situation like boarding atrain without knowing ones destination. Undoubtedly it may result in waste ofprecious time and money.

Student Handbook is purposely designed for the students we have been planningfor some time to provide collective information about academics as well as Instituteto our new comers. It comprises complete information of syllabi of all subjects,Lecture Plans, rules and regulations, internal examinations, marking scheme,attendance, canteen and transport facility etc. However in addition to this, ifstudents 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 isinformation and preparation.We hope that this booklet gives you enough leverage to understand about theinstitute and academics.

Success to a large extent depends on your attitude which includes your sincerityand strong will to vigorously pursue your goal. Its your determination to fulfill therequirements that are needed to enable you achieve your goal. It means you haveto acquire the required academic qualification and skills followed by professionalqualification and training in your particular field. Once you have these, you will be

able to compete.

With Best Wishes
