Justification for CO-PO Mapping
| Mapping | Justification | Affinity level |
| CO1 and PO1 | CO1 is related to understand different aspects of the 3 dimensional Schr ̈odinger equation. This improves student’s knowledge in quantum mechanics and hence the affinity level is 3. | 3 |
| CO1-PO2 | Since PO2 is related to problem analysis and CO1 is also related to solve problems related to 3D Cartesian and spherical polar coordinates. Hence the affinity level between CO1 and PO2 is mentioned as 3. | 3 |
| CO2-PO1 | CO2 is related to learning the main approximation methods for stationary states in quantum mechanics. Hence the affinity level is 3. | 3 |
| CO2-PO2 | As CO2 is related to apply main approximation methods to stationary states. Since PO2 is related to developing analytical skills, the affinity level between them is 3. | 3 |
| CO3-PO1 | Since PO1 is related to acquiring knowledge in quantum mechanics, CO3 has maximum affinity 3 when mapped with PO1. | 3 |
