Iteration 1

Use TDD to create a Student class that responds to the following interaction pattern:

pry(main)> require './lib/student'
# => true

pry(main)> student = Student.new({name: "Morgan", age: 21})    
# => #<Student:0x00007fe196b0c050...>

pry(main)> student.name
# => "Morgan"

pry(main)> student.age
# => 21

pry(main)> student.scores
# => []

pry(main)> student.log_score(89)

pry(main)> student.log_score(78)    

pry(main)> student.scores
# => [89, 78]

pry(main)> student.grade #Average of all the scores
# => 83.5

Iteration 2

Use TDD to create a Course class that responds to the following interaction pattern:

pry(main)> require './lib/course'
# => true

pry(main)> require './lib/student'
# => true

pry(main)> course = Course.new("Calculus", 2)    
# => #<Course:0x00007fa0a69be328...>

pry(main)> course.name
# => "Calculus"

pry(main)> course.capacity
# => 2

pry(main)> course.students
# => []

pry(main)> course.full?
# => false

pry(main)> student1 = Student.new({name: "Morgan", age: 21})
# => #<Student:0x00007fa0a80ae588...>

pry(main)> student2 = Student.new({name: "Jordan", age: 29})    
# => #<Student:0x00007fa0a814f4d8...>

pry(main)> course.enroll(student1)    

pry(main)> course.enroll(student2)    

pry(main)> course.students
# => [#<Student:0x00007fa0a80ae588...>, #<Student:0x00007fa0a814f4d8...>]

pry(main)> course.full?
# => true

Iteration 3

You have been contracted by the University of Denver to write a program that models gradebooks for its courses. Use TDD to implement the following features:

1. Create a Gradebook class. Each gradebook has an instructor, as well as a way to read that data.
2. Each gradebook has courses, as well as a way to read that data.
3. A gradebook can list_all_students in its courses.
4. A gradebook can students_below to return a list of students whose grades are below a given threshold.

Method Name	Return Value (type)
instructor	String
courses	Array of Course objects
add_course(course)	courses (Array of Course objects)
list_all_students	Hash where the key is a Course object and the value is an Array of Student objects
students_below(threshold)	Array of Student objects

Iteration 4

The University of Denver would like you to implement additional functionality. They would like to be able to track all the grades across all courses. They would also like to be able to find all students across all courses that have a grade in a given range.
