Schedule Builder is the website you would use to enroll you in future classes. You can also use it to see which classes you can take at certain times, which specific classes fit to a certain requirement and many more.
Above you can see the first page of what shows up when you go to your schedule builder page. Over here you have options to choose which semester you want to schedule classes in, which could be in Fall, Spring, or Summer. Choose the desired semester you want to schedule classes in and then press continue.
Above what you see is, what happens when you press continue. You can choose which campuses you want to select for what classes you want, the instruction modes you want to take it in, such as if you want asynchronous classes, hybird remote classes, or full in person classes. You can also choose to see if the course is open or not. Schedule builder is a very useful recource.
This is what you see when you press the add course option. Over here you can see that it has the options of: By subject, Search by course attribute, My Planner, Search by instructor, and by Class #. All of these options pretty much let you customize what you want for what kind of class you want when you want it, which professor you want, and the category of class you want. All of these options are there to minimize all your options, which is a huge help. This is pretty much a schedule builder and how it works.
