What's Changed

Grade Aggregate Operations

Performs grade aggregation operations such as mean, median, variance, standard deviation, etc. This command can be performed by entering:
aggGrade OPERATION [n/examName]

Which performs the respective OPERATION on the overall grades of the current filtered person list.

OPERATION can be:

median - median
mean - mean
stddev - standard deviation
var - variance
min - minimum
max - maximum

[n/examName] is optional, and is used to perform OPERATION on a specific exam of the current filtered person list.

Overall Grade Calculations

Added functionality to calculate and display each student's overall grade.
When a new grade is added, the system checks if the total weightage of all grades for a student exceeds 100%.
- If the weightage exceeds 100%, the grade addition is rejected to maintain data consistency.
- This prevents over-allocation of grade weightage, ensuring valid grade distribution.

List Absent Students by Date

Now you can easily list students marked absent on a specified date with a new command. This improves attendance tracking and simplifies follow-ups.
