A Attainment Level.
B Attainment based on internal assessment (CIA) = Average of (a and b);
C Direct CO Attainment Level (DA) =40%CIA + 60% End-Term (C);
D Indirect CO Attainment Level (IA) (based on Exit Survey (d));

To calculate the overall Course Outcome (CO) attainment of a subject, including both internal and external assessments, you can follow these steps:

### 1. **Define the Weights for Internal and External Assessments**
- Determine the percentage weight for internal assessments (e.g., assignments, quizzes, midterms).
- Determine the percentage weight for external assessments (e.g., final exams, projects).

For example:
- Internal Assessments: 40%
- External Assessments: 60%

### 2. **Calculate the Internal Assessment Attainment**
- Collect the scores of internal assessments.
- Calculate the average or weighted average of these scores based on their respective weights.

For example:
- Assignment 1: 85/100
- Assignment 2: 90/100
- Quiz: 80/100
- Midterm: 70/100

If all internal assessments have equal weight, the internal attainment is:
\[
\text{Internal Attainment} = \frac{85 + 90 + 80 + 70}{4} = 81.25
\]

If they have different weights, use the weighted average:
\[
\text{Internal Attainment} = \frac{(85 \times 0.25) + (90 \times 0.25) + (80 \times 0.2) + (70 \times 0.3)}{0.25 + 0.25 + 0.2 + 0.3} = 80.5
\]

### 3. **Calculate the External Assessment Attainment**
- Collect the scores of external assessments.
- Calculate the average or weighted average of these scores.

For example:
- Final Exam: 75/100

If there is only one external assessment, the external attainment is simply:
\[
\text{External Attainment} = 75
\]

### 4. **Combine Internal and External Attainments**
- Use the weights defined in step 1 to calculate the overall CO attainment.

For example:
\[
\text{Overall CO Attainment} = (\text{Internal Attainment} \times \text{Weight of Internal}) + (\text{External Attainment} \times \text{Weight of External})
\]

Using the example weights and scores:
\[
\text{Overall CO Attainment} = (80.5 \times 0.4) + (75 \times 0.6) = 32.2 + 45 = 77.2
\]

### 5. **Express the CO Attainment as a Percentage**
- The final result from step 4 is the overall CO attainment expressed as a percentage.

In summary, to calculate the overall CO attainment, you need to:
1. Define the weights for internal and external assessments.
2. Calculate the internal assessment attainment.
3. Calculate the external assessment attainment.
4. Combine the internal and external attainments using the defined weights.
