Simple Registrar model

Contains classes Student, Professor, Course, Class, Major, and Time

Getting Started

1. Start by creating Courses. Create them using syntax "Course("code", "name", {set of prereqs, optional}, any*)

• * pass True here if only one course from prereqs set is required, leave blank otherwise

2. The next step is to create Majors. Create them using syntax Major("name of major", {set of required courses})
3. Then create Professors using syntax Professor("name", "department", {set of courses optional}, {set of classes optional**}, {set of advisees})

• ** A Class is a particular instance of a course such as CS 208 Fall Term 2022 Section 1

4. Now create Students using syntax Student("name", "grad year", "grad term***", major)

• *** can be "fall", "winter", "spring", or "summer"

5. Finally, create Classes using syntax Class(Course, Term, Year, {set of meet times}, professor, section number. Each item in the set of meet times should be of class Time(Day of the week****, period 1-6****)

• **** Day of the week should be strings "Monday", "Tuesday", "Wednesday", "Thursday", "Friday". If courses meet for two periods together, simply use two Times for that such as {Time("Monday", 2), Time("Monday", 3)}
