Написание программы теста

Здравствуйте дорогие программисты.
Если это возможно прошу помочь с решением проблем
1. Student Registration: Students taking the exam are entered into the grading system via an input file. The file contains the students’ names, ID numbers, and answers to a multiple choice exam.
2. Grading: The user enters an “Answer Key” and then the system grades the students’ answers and calculates the students’ total points, average, and letter grade earned (you are not required to perform data validation);
3. Grade Reporting: The system generates a report (in ascending order) of each student’s name, ID number, exam answers, total points, average and letter grade earned;
4. Analysis Reporting: The system produces three reports (in ascending order) that include the names and graded results of the students who made an A, B, or C (full admission into the program), the names and graded results of the students who made a D (conditional admission into the program), and the names and graded results of the students who failed (F – not admitted to the program);
Due Dates and Honor:
This project will be due by 4:30 pm on Thursday, April 21, 2016. This is a Programming Project, and it is very important that you understand and abide by the policy concerning programming projects (See Academic Integrity Policy below). You are required to complete this assignment independently. If you need help, you should consult with the course tutors or your instructor only. Remember, your personal honor and integrity are far more important than your grade on a project.
Academic Integrity (per the syllabus)
1. In this course, dishonesty in any form will result in the student(s) being dismissed from the course and assigned an “F” at the end of the semester. A report of the Academic Misconduct will be sent to the Registrar’s office. If assignments are copied, both students involved will be dismissed from the course and assigned an “F” at the end of the semester. All assignments must be completed on an individual basis.

Detailed Specification:
1. Student Registration:
The system will read the students’ ID number (an integer), full name (name will be the format: last name, first name), and the students’ 10 multiple choice answers from an input file provided.
2. Grading:
The exam consists of 10 multiple-choice questions. The answer key is entered by the user. Valid choices for each of the exam questions are A, B, C, or D.
3. Grade Reporting:
A report will be produced, sorted in ascending order by name, displaying all the students’ information. (See the report in the Sample Input/Output section.)
4. Analysis Reporting:
Three separate reports will be produced, sorted in ascending order by name, and grouped in the following categories:
a) Admitted into the Graduate Program (students who earned an A, B, or C);
b) Conditional Admission (students who earned a D);
c) Admission Denied (students who earned an F).
(See the report in the Sample Input/Output section.)
Solution Design:
Function decomposition: accomplish each specified task with well designed modular functions.
Solution integration: integrate the modules into a prototype (a working model) for an exam software system.
All coding standards should be followed. You are not required to perform data validation or have the program repeatable.
What to submit and how it will be graded:

Заранее большое спасибо за вашу помощь

• Design, Develop, Implement, and Test: You will only submit the tested integral prototype with full functionality if you completed them successfully. Otherwise, you may submit a solution with partial functionalities. This means you will submit your solution for the highest numbered step that actually works. For example, if you had a working solution to Step 3, but only a partially complete solution to Step 4, you would submit your Step 3 solution. Each of the four required functionalities is worth 25 points for a total of 100 combined points. Submit your .cpp file via the Exams link on the Blackboard menu.
