Introduction
In today's educational environment, the efficient management of student scores and grades is essential for both teachers and students. This report presents a solution for a program that calculates the final score and letter grade for a student based on their homework, tests, project, and final exam scores using a defined grading system. The program will include modules for score validation to ensure that the scores entered fall within acceptable ranges.
Grading System Overview
The program calculates the scores based on the following criteria:
- Homework Assignments: There are 7 assignments, each worth 7 points. The lowest score is dropped, yielding a maximum of 42 points.
- Proctored Open-book Tests: There are 5 tests, each worth 7 points. Like the homework, the lowest score is dropped, giving a maximum of 28 points.
- Project: The project contributes a maximum of 10 points.
- Final Exam: The final exam is worth a maximum of 20 points.
The letter grades correspond to the following percentages:
- A = 90 – 100%
- B = 80 – 89%
- C = 70 – 79%
- D = 60 – 69%
- F = 0 – 59%
Program Structure
The program will be divided into the following key modules:
1. Input Module: This module collects input from the user for homework, tests, project, and final exam scores.
2. Validation Module: It validates the scores to ensure they are within the acceptable range.
3. Score Calculation Module: It calculates the total score and determines the letter grade based on final calculations.
4. Main Module: The main function that orchestrates the execution of the previous modules.
Module Implementation
Here is the Python implementation of the described modules.
```python
def validate_score(score, max_score):
"""Validate that the score is within the range 0 to max_score."""
if 0 <= score <= max_score:
return True
return False
def input_scores():
"""Collect and validate scores from user input."""
homework_scores = []
print("Enter scores for 7 homework assignments:")
for i in range(7):
while True:
try:
score = float(input(f"Homework {i + 1} score (0-7): "))
if validate_score(score, 7):
homework_scores.append(score)
break
else:
print("Score must be within the range of 0 to 7.")
except ValueError:
print("Please enter a valid number.")
homework_scores.remove(min(homework_scores))
test_scores = []
print("Enter scores for 5 proctored open-book tests:")
for i in range(5):
while True:
try:
score = float(input(f"Test {i + 1} score (0-7): "))
if validate_score(score, 7):
test_scores.append(score)
break
else:
print("Score must be within the range of 0 to 7.")
except ValueError:
print("Please enter a valid number.")
test_scores.remove(min(test_scores))
while True:
try:
project_score = float(input("Enter the project score (0-10): "))
if validate_score(project_score, 10):
break
else:
print("Score must be within the range of 0 to 10.")
except ValueError:
print("Please enter a valid number.")
while True:
try:
final_exam_score = float(input("Enter the final exam score (0-20): "))
if validate_score(final_exam_score, 20):
break
else:
print("Score must be within the range of 0 to 20.")
except ValueError:
print("Please enter a valid number.")
return homework_scores, test_scores, project_score, final_exam_score
def calculate_final_score(homework_scores, test_scores, project_score, final_exam_score):
"""Calculate the final score out of 100."""
total_homework = sum(homework_scores) # total homework after dropping lowest
total_tests = sum(test_scores) # total tests after dropping lowest
final_score = total_homework + total_tests + project_score + final_exam_score
return final_score
def determine_letter_grade(final_score):
"""Determine the letter grade based on the final score."""
if 90 <= final_score <= 100:
return 'A'
elif 80 <= final_score < 90:
return 'B'
elif 70 <= final_score < 80:
return 'C'
elif 60 <= final_score < 70:
return 'D'
else:
return 'F'
def main():
"""Main function to run the program."""
homework_scores, test_scores, project_score, final_exam_score = input_scores()
final_score = calculate_final_score(homework_scores, test_scores, project_score, final_exam_score)
letter_grade = determine_letter_grade(final_score)
print(f"\nFinal Score: {final_score} - Letter Grade: {letter_grade}")
if __name__ == "__main__":
main()
```
Explanation of the Program
1. Score Validation: The `validate_score` function ensures the score entered is within the permissible limits for each type of assessment.
2. Input Collection: The `input_scores` function gathers scores from the user while simultaneously validating the inputs and dropping the lowest score in the homework and tests.
3. Score Calculation: The `calculate_final_score` function computes the total score by summing the individual components.
4. Grade Assignment: The `determine_letter_grade` function assigns a letter grade based on the calculated score.
5. Main Function: This function orchestrates the flow of the program, allowing for interactive user input and elegant output of results.
Conclusion
This program effectively fulfills the requirements outlined in the ITP100 project by calculating a student's final score and corresponding letter grade based on specific grading criteria. The modular design ensures that the code is clean, maintainable, and easy to enhance in the future.
