How can students verify the correctness of CGPA to percentage conversion?

 Students at SPPU can verify the correctness of their CGPA to percentage conversion by following a systematic approach, because the university’s CGPA system is credit-weighted and each course contributes differently. Here’s how to do it:

---

1. Know the CGPA to Percentage Formula

SPPU generally uses:

$$\text{Percentage} = \text{CGPA} \times 10$$

• For example, CGPA 7.2 → 72%

• This is the official conversion, but it assumes the CGPA was calculated correctly.

2. Check Individual Course Calculations

To be sure the CGPA is correct:

1. List all courses taken in the program.

2. Note the credit and grade point for each course.

3. Use the credit-weighted formula:

$$\text{CGPA} = \frac{\sum (\text{Grade Point} \times \text{Credits})}{\sum \text{Credits}}$$

4. Multiply the resulting CGPA by 10 to get the percentage.

3. Compare with Official Marks

• Compare your calculated percentage with the percentage shown on the official mark sheet.

• Small differences may occur if the university rounds CGPA differently.

---

4. Verify SGPA per Semester

• Check each semester’s SGPA using the same formula:

$$\text{SGPA} = \frac{\sum (\text{Grade Point} \times \text{Credits in that semester})}{\sum \text{Credits in that semester}}$$

• Then ensure final CGPA is the credit-weighted average of all SGPAs.

5. Ask the University (if needed)

• If there’s a mismatch, SPPU allows students to request a re-check or verification of marks/CGPA through the exam cell.

• Keep course grade cards and credit info ready for reference.

✅ Tip: The key is ensuring that grade points × credits for all courses add up correctly and the credit totals are accurate. Mistakes usually happen in credit weightings or rounding errors.
