Evaluation of Student’s Performance

The total performance of a student in a given course will be evaluated on the basis of a scheme of Continuous assessment, In-course examinations and Course Final examinations.

1. Marks Distribution for Courses: The distribution of marks for theoretical and practical courses will be as follows:

____________________________________________

Class attendance/participation 5%

In-course assessment 35%

Course Final Examination 60%

____________________________________________

2. Continuous Assessment: The continuous assessment for theory courses will be made through a set of in-course examinations and class attendance/participation; and for practical course (laboratory/field works/short project), it will be made through class attendance/participation, assignments, evaluation of interactive skills and laboratory reports/project reports. The scheme of continuous assessment will be announced by the course teacher(s) at the beginning of the course.
3. Class Attendance/Participation: A student must attend at least 75% of the total classes held in an academic year to be eligible for appearing in the Course Final examinations. A student attending at least 60% classes but less than 70% classes will be allowed to appear for the examination after paying non-collegiate fees fixed by the University and student attending less

than 60% classes will not be allowed to appear for the Final examination for that year/session. Basis on the awarding marks for class attendance will be as follows:

__________________________________________

Attendance (% of the total class held) Marks (%)

95 and above 5

85 to less than 90 3

80 to less than 85 2

75 to less than 80 1

Less than 75 0

__________________________________________

4. In-course Assessment: In-course tests of minimum one hour duration shall be conducted and evaluated by the course teacher(s). There will be at least 2 (two) written tests for 3/4-credit courses and at least 1 (one) test for 2-credit courses. Additional assessment may be made by the course teacher(s) prior approval by the Academic Committee of the Department. The question patterns for in-course tests should preferably be of objective type. The Course teacher will show the assessed in-course scripts to the students and shall announce the results within two weeks of the date of holding the test.

Make-up test will be arranged for a student who fails to appear in in-course test/tests due to unavoidable circumstances like accident, medical surgery, parent has expired or such situations prior approval of the Academic Committee of the Department and the test must be held during the course period. Absence in any in-course test will be counted as zero for calculating the average marks for that in-course test.

5. Course Final Examination: The Course Final examination for theoretical course will be conducted centrally by the Controller of Examinations as per University Rules. The examination will be of 3 hours duration for 4-credit course and 2 hours for 2-credit course. The question patterns for Course Final tests should be defined by the Department.

For evaluation of the Course Final examination for theoretical courses there will be two examiners: one internal (will be course teacher or teachers) and the other external (will preferably be within the Department/University provided that he/she is not a course teacher for the course paper to be examined). Under the double examiner system and in case of difference more than 20% of marks, there will be a 3^rd examiner for evaluation and marks of the nearest two examiners will be calculated for average out as final marks.

6. Assessment of Seminar/Project/Internship: The mode of assessment of Seminar/Project/Internship will be determined by the respective Departmental Examination Committee approved by the University.
7. Viva-Voce: A regular student must appear at the Viva-voce/Oral examination at the end of the Course Final examinations and it will be conducted by the respective Departmental Examination Committee approved by the University.

Grading System

A basic four-point (4.00) grading scale will be followed and marks obtained for each course will be converted to grades. The following letter grades and corresponding grade-points will be used to determine the student’s grade point average (GPA).

Marks Obtained	Corresponding Letter Grade	Grade point	Grade Description
80% or above	A+	4.00	Grade A: Exceptional performance; all course objectives achieved; objectives met in a consistently outstanding manner.
75% to less than 80%	A	3.75	- Do -
70% to less than 75%	A-	3.50	- Do -
65% to less than 70%	B+	3.25	Grade B: Very good performance; significantly more than the majority (at least two-thirds) of the course objectives achieved; objectives met in a consistently thorough manner.
60% to less than 65%	B	3.00	- Do -
55% to less than 60%	B-	2.75	- Do -
50% to less than 55%	C+	2.50	Grade C: Satisfactory performance; al least majority of the course objectives achieved; objectives met satisfactorily
45% to less than 50%	C	2.25	- Do -
40% to less than 45%	D	2.00	Grade D: Minimally acceptable performance; less than majority but more than the minimum required course objectives achieved; objectives achieved at a minimally acceptable level.
Less than 40%	F	0.00	Grade F: Failed in the course

A course in which a student has obtained “D” or higher grade will be counted as credits earned by him/her and obtained “F” grade will not be counted towards his/her earned credits.

Calculation of GPA and CGPA

Grade Point Average (GPA) is the weighted average of the grade points obtained in all courses passed/completed by a student in an academic year. The GPA is computed in the following manner:

GPA = ?PE/ ?Cr

Where, PE means Points Earned (i.e. Grade Points x Credits) and Cr means Credits attempted in the year.

The Cumulative Grade Point Average (CGPA) for the 2^nd year, 3^rd year and 4^th year results is computed by dividing the total accumulated grade points earned up to date by the total credit points attempted.

Promotion to Higher Class

1. Promotion from 1^st year to 2^nd year: A student must earn a minimum GPA of 2.00 and must have passed (minimum ‘D’ grade) all the courses taken for promotion. Students who failed in courses (maximum 8 credit hours) but have earned the required GPA 2.00 will be promoted on probation, and those on probation shall appear at the retake examination and must pass the failed course(s) to be allowed to continue studies in the 2^nd year.
2. Promotion from 2^nd year to 3^rd year: A student must have earned a minimum CGPA of 2.25 and must have passed (minimum ‘D’ grade) all the courses for promotion. Students who failed in courses (maximum 8 credit hours) but have earned the required CGPA 2.25 and students who earned CGPA less than 2.25 but equal to or more than 2.00 without ‘F’ grade will be promoted on probation. Those on probation shall appear at the retake examination and must pass the failed course(s) to be allowed to continue studies in the 3^rdyear.
3. Promotion from 3^rdyear to 4^th year: A student must have earned a minimum CGPA of 2.50 and must have passed (minimum ‘D’ grade) all the courses for promotion. Students who failed in courses (maximum 8 credit hours) but have earned the required CGPA 2.50 and students who earned CGPA less than 2.50 but equal to or more than 2.25 without ‘F’ grade will be promoted on probation. Those on probation shall appear at the retake examination and must pass the failed course(s) to be allowed to continue studies in the 4^th year.

Retake Examination

1. Student on probation for failing in the final examination course(s) must sit for Retake examination of the failed course(s) within 6 weeks after publication of results, conducted by the respective original Examination Committee of the year and expenses of the Retake examinations, as determined by the University authority, must be borne by the student(s). If a student achieves the required credits in the retake examination, he/she will be considered as promoted and his/her letter grade for that course will be preceded by the letter ‘P’ in the transcript. If any student fails to earn the required credits, his/her promotion on probation will be deemed cancelled.
2. Student on probation for failing to earn requisite CGPA without any ‘F’ will be allowed to sit at Retake examination for a maximum of 8 credits (including practical and viva-voce) under the same conditions mentioned above as determined by the University. If a student succeeded to earn the required CGPA, he/she will be considered as promoted and his/her letter grade for that course will be preceded by the letter ‘P’ in the transcript. If any student fails to achieve the required CGPA, his/her promotion on probation will be deemed cancelled.
3. Students who failed in maximum of 8 credits of the 4^th year, he/she must sit for Retake examination of the failed courses under the same conditions mentioned above as determined by the University. After the Retake examination, if a student achieves required credits, he/she will be considered for graduation and his/her letter grade for that course will be preceded by the letter ‘P’ in the transcript.

Improvement of Grade points

1. To improve GPA or CGPA, a student may appear at the final examination (theory course, practical course or viva-voce), only once, with the following next batch in a maximum 8 credits in each year and the student shall apply to the Chairman of the department for improving the grade at least 8 weeks before the start of the final examination. Improved grade point will be used for GPA and CGPA. The transcript will have a symbol “I’ identifying the improved course.
2. If a student desire to improve the grade point earned in a course of 4^th year, he/she must apply for such improvement examination before the award of the degree (i.e. before issuance of certificate). Improvement shall not be allowed once the degree is awarded.

Drop out

A student failing to earn the required minimum GPA/CGPA and/or to earn requisite credits after retake examination, he/she may take readmission with the approval of the Academic Committee of the department to appear in the course final examination with the next batch.
