Q4: Can I use this for more than 5 subjects?
A: No, this calculator is specifically for 5 subjects. For different numbers, adjust the formula accordingly.
Q5: Does this account for credit hours or subject weight?
A: No, this is a simple average. For weighted calculations, use a weighted average calculator.
