The score for each user is calculated based on their marks and the time taken (duration_millisecond). The equation for the score is:

$\text{Score} = (w_m \times \text{Normalized Marks}) + (w_d \times \text{Normalized Duration})$

where:

• $\text{Normalized Marks} = \frac{\text{Marks} - \text{Min Marks}}{\text{Max Marks} - \text{Min Marks}}$
• $\text{Normalized Duration} = 1 - \frac{\text{Duration} - \text{Min Duration}}{\text{Max Duration} - \text{Min Duration}}$

The weights $w_m$ and $w_d$ are used to emphasize marks and duration, respectively, with typical values like $w_m = 0.7$ and $w_d = 0.3$. This scoring method encourages high marks and efficient completion time by balancing accuracy and speed.
