What is SGPA in SPPU and how does it differ from CGPA?

 1. What is SGPA?

SGPA stands for Semester Grade Point Average.

• It measures a student’s performance in a single semester.

• Like CGPA, it’s on a 0–10 scale.

• Each subject’s grade points are weighted by its credits.

Formula to calculate SGPA:

$$\text{SGPA} = \frac{\sum (\text{Grade Points} \times \text{Credits})}{\sum (\text{Credits})}$$

Note: This is exactly the same formula as CGPA, but applied only to one semester.

2. Example of SGPA

Suppose in Semester 3, a student has these grades:

Subject	Credits	Grade	Grade Points
Maths	4	A	8
Physics	3	B+	7
Chemistry	3	O	10

Step 1: Multiply grade points by credits:

• Maths: 8 × 4 = 32

• Physics: 7 × 3 = 21

• Chemistry: 10 × 3 = 30

Step 2: Sum them: 32 + 21 + 30 = 83

Step 3: Sum total credits: 4 + 3 + 3 = 10

Step 4: Divide: 83 ÷ 10 = 8.3 SGPA

3. Difference between SGPA and CGPA

Feature	SGPA	CGPA
Meaning	Semester Grade Point Average	Cumulative Grade Point Average
Scope	One semester only	All completed semesters
Formula	Weighted average of grades in that semester	Weighted average of all grades across semesters
Use	Shows performance in a single semester	Shows overall performance throughout the course

✅ Key point:

• You first calculate SGPA for each semester.

• Then CGPA is calculated using all SGPAs, weighted by semester credits.
