Build your UMD class schedule the easy way

Schedule builder
Pick your courses and sections, then drag them onto a weekly grid. Conflicts are flagged the moment two sections overlap so you never register for an impossible combo.
Saved schedules
Save multiple drafts and switch between them. Compare a MWF-heavy week against a TTh schedule before you commit to one during registration.
Auto-generate
Tell Orbit which courses you need, set preferences like no 8am sections or keep Fridays free, and it produces a conflict-free schedule automatically.
Real-time section data
Section times and seat availability come from the UMD course catalog. What you see in Orbit matches what you'll find when you go to register.
Why students use it before registration opens
Registration at UMD moves fast. Having a schedule already mapped out means you can add courses in order of priority the moment your window opens, without scrambling to figure out which sections fit together. Orbit also connects to your four-year plan and degree audit, so you're always registering for courses that actually count toward graduation.
A UMD course planner that goes beyond Testudo
Testudo shows open sections but doesn't help you build a conflict-free weekly schedule or compare what-if plans before you register. Orbit is a free UMD class schedule maker: pick courses, drag sections onto a grid, and let the auto-generator produce registration-ready options. Use it as your course planner for the whole semester—not just on registration day.
Frequently asked questions
Is the schedule builder free?
Yes. Building, saving, and auto-generating schedules is free for every UMD student. No upgrades, no paywall.
How many schedules can I save?
As many as you want. Save a backup for each registration scenario and come back to them any time.
Does it check for time conflicts automatically?
Yes. As soon as two sections overlap on the weekly grid, Orbit flags the conflict. You cannot accidentally save a schedule with back-to-back conflicting courses.
Can I use this alongside my four-year plan?
Yes. Courses you add to a semester in your four-year plan feed directly into the schedule builder for that term, so you're always working from the same source of truth.
