FOREWORD

The GVP college of Engineering (Autonomous) has entered into a new

phase as it completed one cycle of autonomy. Recently the Autonomy has

been extended for six more years(2014-2020) by UGC, the affiliating

University JNTU-K. The experiences with the experiments and innovations

brought into the curriculum with the help of autonomy are proving

successful and encouraging.

The paradigm shift in the curriculum design has been brought into the

system in 2013 in the form of Out Come Based Education (OBE) and the

systems and processes are stabilized in this regard.

Recently, the Choice Based Credit System (CBCS) has been introduced

along with the grading system as per the guidelines of UGC, to offer more

choice, facilitate the cross mobility and uniformity across the country.

The concepts of Pedagogical training and Industrial training are also

introduced after II semester as an elective to enable the graduates sharpen

their skills.

Credits are introduced for Dissertation work to infuse more seriousness

and as a qualitative measure of the work carried out.

I thank all the expert members, Industry representatives, University

representatives and all other members on Boards of Studies, Academic

Council who helped us in brining a good shape to the curriculum.

I also thank the members of the Governing Body for their constant support

and guidance in all our academic endeavors.

I hope with these changes, the curriculum will be more beneficial to the

students to make them ready to face the elite society and the challenges

ahead.

9.1 Computation of Semester Grade Point Average (SGPA) and

Cumulative Grade Point Average (CGPA):

The SGPA is the ratio of sum of the product of the number of credits

with the grade points scored by a student in all the courses taken by a

student and the sum of the number of credits of all the courses

undergone by a student in a semester, i.e

SGPA (Si) = Σ(Ci x Gi) / ΣCi

where Ci is the number of credits of the ith

course and Gi is the grade

point scored by the student in the ith

course.

The CGPA is also calculated in the same manner taking into account all

the courses undergone by a student over all the semesters of a

programme, i.e.

CGPA = Σ(Ci x Si) / Σ Ci

where Si is the SGPA of the ith

semester and Ci is the total number of

credits in that semester. The SGPA and CGPA shall be rounded off to 2

decimal points and reported in the transcripts.

Transcript for each semester shall be issued containing letter grades and

grade points along with attendance grade, for each of the courses

registered, SGPA of that semester and CGPA up to that semester. Marks

will not be displayed on the transcript.

A consolidated transcript indicating the performance in all semesters

shall also be issued.

Note: The CGPA ranges for the award of class or division shall be as

decided by the affiliating University.

9.2 AWARD OF THE M.TECH. DEGREE: A student shall secure a

pass in all courses corresponding to 80 credits to be eligible for the

award of the M.Tech. degree.

9.3 PROVISION FOR IMPROVEMENT OF CGPA: A student shall

be permitted to improve his class or division from PASS CLASS to

SECOND CLASS or SECOND CLASS to FIRST CLASS after

successful completion (passing all the courses) of the programme. He /

She may be allowed to appear for supplementary examinations and earn

indiscipline is pending against him, the result of the candidate shall be

withheld and he will not be allowed into the next higher semester. The

recommendation for the issue of the degree shall be liable to be withheld

in all such cases.

11. TRANSITORY REGULATIONS:

attendance or who has failed after having studied the course, is eligible

for admission to the same or equivalent course(s) as and when

course(s) is/are offered, subject to 5.0 and 2.0.

b. Credit equivalences shall be drawn for the students re-admitted into
