Letter Grade: It is an index of the performance of students in a said

course. Grades are denoted by letters O, A+, A, B+, B, C, P and F.

Based on the marks secured, a Grade Point is awarded for each theory

course / lab course / dissertation work / Pedagogy Training / Industrial

Training along with a corresponding Letter Grade as per the following:

Grades and Grade Points

Letter Grade Grade

Point

O (Outstanding) 10

A+ (Excellent) 9

A (very good) 8

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.


M.TECH-CAAD viii

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.

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

minimum of P grade 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 CGPA upto a maximum of ‘7’ after

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

She may be allowed to appear for supplementary examinations and earn

grade points for improvement from at the most two courses of his / her

choice. The improvement provision shall be limited to one attempt.

10. WITHHOLDING OF RESULTS:

If the candidate has not paid any dues to the college or if any case of

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.
