Continuous Assessment Test (CAT) CAT-1, CAT-2 & CAT-3 (Best Two CAT Marks)	Model Exam	Assignment	University Examination (50% Weightage)
10 Marks + 10 Marks	15 Marks	15 Marks	50 Marks

A student has to score a minimum of 50 marks aggregate in both internal and external for getting pass mark. Continuous Assessments Test CAT-1 normally in two learning units prescribed by the Course Coordinator, CAT-2 in two learning units and Model Examination in all the five learning units are generally conducted as Written Assessments of duration 90 minutes, 90 minutes and 180 minutes respectively. Assignment marks is calculated based on writing practice, problem solving, seminar, quiz, Tech. Talk, etc.

Assessment for Laboratory Courses

For Practical Subjects, the internal mark is calculated for 50 marks and the weightage is given and calculated based on experiments, observations, collection of data, analysis, interpretation of results, inferences and timely submission of record work done based on the type of laboratories and model practical examinations and the weightage is as given below.

The University Practical Examination shall be conducted with an External Examiner and the course handler as internal examiner for 50 marks. The external examiner shall be appointed by the Controller of Examinations/Dean /Principal from the panel of examiners recommended by Chairman, Board of Studies in respective Branches.

Internal Practical Marks (50) + External Practical Marks (50) = 100 Marks

Passing Requirement

• The Passing requirement for a student in a course is determined based on the marks obtained both in Continuous Assessment and End Semester Examinations. If the student gets <50% of total marks, then the student will be awarded only F (Fail) grade.
• If a candidate fails in the seventh semester examinations of Project 1, he/she has to resubmit the Project Report within 30 days from the date of declaration of the results. If he / she fails in the End semester examination of Project 2 of B.Tech. or the Final Project work of B.Tech, he/she shall resubmit the Project Report within 60 days from the date of declaration of the results. The resubmission of the project report and the subsequent viva- voce examination will be considered as reappearance with payment of exam fee. In case a student fails in the resubmission of a project report and subsequent viva-voce examination, the student shall register for the course again, when offered next
• Supplementary Examinations If a student fails to secure a pass in theory course(s) of VIII semester examination, he/she is eligible to appear for a one time Supplementary Examination which shall be conducted at the end of VIII semester, for the subjects of VIII semester alone within 30 days from the date of declaration of the results.
• End semester valuation clarification day For a theory course where there is an end semester examination, a valuation clarification day shall be conducted within 10 - 15 days from the date of the last examination. The date of the clarification day for each course shall be announced by the Dean concerned. On this day, the students can view their end semester answer papers in the presence of the course instructor and get any clarifications / corrections done. In cases of dispute, where the student is not satisfied with the clarifications / corrections, the matter can be referred to a committee, consisting of the Dean of the courses concerned / HOD nominee, concerned course instructor and a subject expert. In case a student does not attend the valuation clarification day on the specified date, no further clarifications will be entertained. The results will be published after the end semester valuation clarification day
• For the award of B. Tech. Degree, a student has to acquire a maximum of 160 to 170 learning credits by learning and practicing the various courses prescribed in the curriculum within the stipulated time duration.

Award of Letter of Credit

Letter Grades and Grade Points (GP) are earned by the student for each course based on the aggregate of marks obtained through continuous learning assessments and end-semester final examination.

Letter Grade	Grade Point	Mark Range
O (Outstanding)	10	91– 100
A+ (Excellent)	9	81– 90
A (Verygood)	8	76– 80
B+ (Good)	7	71– 75
B (Above Average)	6	61– 70
C (Average)	5	50– 60
F (Fail)	0	<50
AB (Absent)	0	Absent in Examination
SA (Shortage of Attendance)	0	Lack of Attendance

SGPA and CGPA Calculation.

The grade card issued by the Controller of Examinations to each student, after the announcement of the results will contain the following

• The credits for each course registered for that semester
• The letter grade obtained in each course
• The attendance code in each course
• The total Grade number of credits earned by the student up to the end of that semester
• The Semester Grade Point Average (SGPA) and the Cumulative Grade Point Average (CGPA) of all the courses taken from the I semester onwards for regular students and from III semester onwards for lateral entry students.

Computation of Semester Grade Point Average (SGPA) and Cumulative Grade Point Average (CGPA) ∑1nCi X (GP)i

• SGPA will be calculated according to the formula: SGPA = ∑1nCi Where Ci = Credit for ithCourse, (GP)i = the Grade Point obtained for the ithCourse, n = Total number of course taken in the semester, including those in which the students has secured the F grade. ∑1rSi X (SGPA)i
• CGPA will be calculated according to the formula: CGPA = ∑1nSi Where Si = Sum of credits in ithsemester, (SGPA)I= Semester Grade Point Average earned in ithSemester and r = number of semester and the sum is over all the semester under consideration.
• The SGPA and CGPA shall be rounded off to 2 decimal point and reported in the transcripts.
