🏛️ About JNTUH
Established in 1972, JNTUH oversees numerous affiliated colleges across Telangana. It maintains strict academic regulations like R22, R18, R16, and R15 which define the structure of examinations, grading patterns, and course credits.
📘 Grading System Explained
JNTUH uses a 10-point grading system to evaluate student performance. Here's a breakdown:
O (10): Outstanding (90–100%)
A+ (9): Excellent (80–89%)

📊 How SGPA & CGPA Are Calculated
SGPA is calculated per semester using the following formula:
SGPA = Σ (Credit × Grade Point) / Σ Credits
CGPA is the cumulative average of all SGPAs obtained over the duration of your program.
This is important for students applying to higher studies or appearing in placement interviews, where CGPA often plays a significant role.
📌 Real-Life Example of CGPA Calculation
Let’s say you have the following semester GPAs:
- Sem 1: SGPA 8.5 (25 credits)
- Sem 2: SGPA 7.8 (24 credits)
- Sem 3: SGPA 9.0 (26 credits)
CGPA = (8.5×25 + 7.8×24 + 9.0×26) / (25 + 24 + 26) = 8.46
