CO-PO Justification

Mapping Justification Affinity level
CO1-CO4 to PO1 and PSO 1 This course is a fundamental course with objective of building strong core fundamentals; hence, all the course outcomes have very strong affinity to PO1 and PSO 1, which is about building fundamentals in science, and create inquisitiveness and problem solving in scientific way. Hence the affinity level is maximum. 3
CO1-CO4-PO2 and PSO2 This course is a fundamental course with objective of building strong core fundamentals; hence, all the course outcomes have very high affinity to PO2 and PSO2, which is about building analytical thinking, which is a core skill in scientific investigation. Hence the affinity level is maximum. 3
CO1-CO4 – PO3 This course is a fundamental course with objective of building strong core fundamentals; hence, all the course outcomes have very high affinity to PO3, which is about undertaking complex problems and to design and develop solutions which enhance the existing scientific knowledge. Hence the affinity level is maximum. 3
