🧮 Core Algorithm

🔢 Mathematical Formula

// IITM Official Formula
Assignment_Score = (Σ assignments / 10) × 0.1
Method_1 = (Final × 0.6) + (max(Quiz1,Quiz2) × 0.2)  
Method_2 = (Final × 0.4) + (Quiz1 × 0.2) + (Quiz2 × 0.3)
Total = Assignment_Score + max(Method_1, Method_2)
CGPA = Σ(Grade_Points × Credits) / Σ(Credits)

🎖️ Grade Scale

📊 Score	🏆 Grade	💎 Points	📊 Score	🏆 Grade	💎 Points
90-100	S	10	50-59	D	6
80-89	A	9	40-49	E	5
70-79	B	8	0-39	F	0
