Workshop Questions

1. Write a program that asks the user to input the number of students of a class named

BIS1003. The program then will ask the user to input: the ID, Assignment 1 marks,

Assignment 2 marks and Final Exam marks for every student. The program needs to

validate the marks out of 100. Use a dictionary to store the ID and marks of the

students. After the user finishes entering the students' info, the program should

display the student ID and their marks. The program should be able to handle

exceptions.

marks of the assignments and the Final Exam. Weight of Assignment 1, Assignment

2 and Final Exam can be 25%, 25% and 50%, respectively. The program should

display the final result as follows:
