Attainment Calculation
Direct Attainment
1. Internal Test
Three tests will be conducted then evaluated Marks will be grouped to respective CO
Attainment level for each CO is calculated by % of students achieving Threshold. Internal Test Threshold
= 50 Marks.
Attainment Level = 3 / 2 / 1 if ≥80 % / ≥70 % / ≥60 % of students’ scores ≥ 50.
Average of all COs for 3 tests is Internal Test Attainment.
2. Assignment
Three assignments will be given then evaluated Marks will be grouped to respective CO
Attainment level for each CO is calculated by % of students achieving Threshold.
Internal Assignment Threshold = 80 Marks
Attainment Level = 3 / 2 / 1 if ≥80 % / ≥70 % / ≥60 % of students’ scores ≥ 80.
Average of all Cos for 3 Assignments is Internal Assignment Attainment.
Internal Attainment = 0.7 * Internal Test Attainment + 0.3 * Internal Assignment Attainment
3. University Exam
Attainment level is calculated by % of students achieving Threshold.
University Exam Threshold = 50 marks
Attainment Level = 3 / 2 / 1 if ≥80 % / ≥70 % / ≥60 % of students’ scores ≥ 50
Direct Attainment = 0.6 * University Exam Attainment + 0.4 * Internal Attainment
Indirect Attainment
Course Exit Survey
Course Exit Survey will be conducted. Average marks for feedback questions will be calculated
Attainment level is calculated by % of students achieving Threshold. Threshold = 80 % Marks
Attainment Level = 3 / 2 / 1 if ≥80 % / ≥70 % / ≥60 % of students’ scores ≥ 80.

CO Attainment = 80 % of Direct Attainment + 20 % of Indirect Attainment
