The fast lane through TSS.
Book a class in one click, schedule your enrollment for the second your window opens, and see every section, professor rating and grade distribution without leaving TSS.
Unofficial. Not affiliated with UC San Diego. Read before you install.
Screenshot coming soonEverything TSS doesn’t show you.
TridentSpeed works inside TSS with your own sign-in, and adds a full-tab planner. Here’s what you get.
Book in one click. Or schedule it for your window.
TridentSpeed sends TSS’s own booking request straight from the planner, so you skip TSS’s booking pages. Line up sections in the order you want them, and it enrolls them one at a time.
- Schedule a run for your enrollment window. It goes by TSS’s own clock, and keeps trying while TSS says your window isn’t open yet.
- Waitlist when a section is full, if you choose.
- Watch a full section: get a notice, or have it booked, when a seat opens.
- After every try it checks TSS again, so you see what actually happened.
Screenshot coming soonEvery section, side by side.
Open a course and see all of its sections at once: times, rooms, live seats and waitlists, instructors with their ratings, and finals. Each one is marked if it fits your plan.
- Search by course, subject, title or instructor.
- Filter by open seats, days, times, level, or prerequisites you’ve met.
Screenshot coming soonRatings right inside TSS.
Open any course in TSS’s Schedule of Classes, and a panel lists every section with professor ratings and any conflict with the classes you’re in.
- When TSS throws a 503 error page, it reloads for you.
- When TSS says a course has no sections but its data lists some, it tells you.
Screenshot coming soonSee your week before you book.
Build a few plans for the quarter and switch between them. Time conflicts and finals that clash stand out, and you can export a plan to your calendar.
- Several named plans per quarter, with units and conflicts.
- Your booked classes can show on the same week.
Screenshot coming soonKnow how far the next class is.
Pick a day and see your classes as numbered stops, with real walking routes between them. Walks longer than your break are flagged.
- Map, colorful and satellite styles, plus 3D.
Screenshot coming soonPast grades and professor ratings, in one place.
See the grades a course and its instructors have given in past quarters, from UCSD’s SET results with your own UCSD sign-in, next to a breakdown of their RateMyProfessors ratings.
- For the course overall, for one instructor, and for their latest quarter.

Before you install
TridentSpeed is new, unofficial, and made by a UCSD student. Here’s what it can’t do, and what it sends.
The limits
- Scheduled runs need Chrome open, your computer awake, and you signed in to TSS (Duo included) when your window opens.
- It can’t make seats appear. TSS is often slow or busy. TridentSpeed keeps trying, but nothing guarantees a seat.
- It needs Chrome, Edge, Brave or Arc on a computer. Not Safari, Firefox, or a phone.
- It runs with Developer mode on, from outside the Chrome Web Store, and doesn’t update itself. New versions come from this page.
- It’s unofficial. UCSD doesn’t support it, and a change to TSS can break part of it until an update.
- Ratings are left out when a name could match two professors. Grade data needs a SET sign-in, and a big course can take a few minutes the first time.
- There will be bugs. Please tell us: tridentspeeducsd@gmail.com.
Your data
TridentSpeed runs in your browser, with your own TSS session. Some of what you do in it is sent to TridentSpeed’s server:
- Your UCSD email address, your name and your student ID number
- Your registration window
- The classes you add to plans, and the sections you pick
- Your past classes with grades, what you’re registered for, your class standing and your major
- Your seat watches and scheduled runs
- Anonymous numbers about how fast things ran
Never sent
Your password, SET results, RateMyProfessors data, and the names of your plans. Everything else stays in your browser.
Good to know
- It’s on for everyone who installs it. There’s no switch to turn it off. Incognito windows never send.
- Only the developer can see it. No IP addresses or request logs are kept.
- It’s kept until you ask for it to be deleted: email tridentspeeducsd@gmail.com.
FAQ
Does it see my password?
No. It uses the TSS session you’re already signed in to in your browser, the same way TSS’s own pages do. Your password and Duo stay between you and UCSD.
Why does it need Developer mode?
TridentSpeed isn’t in the Chrome Web Store, and Chrome only runs extensions from outside the store while Developer mode is on. Leave it on, or Chrome turns TridentSpeed off.
How do I update it?
Download the new version from this page and drag it onto your extensions page, the same way you installed it. It replaces the old version and keeps your plans.
Is it free?
Yes. No account, no ads, no payment.
Does it work on my phone, or in Safari or Firefox?
Not yet. It needs Chrome, Edge, Brave or Arc on a computer.
Who makes it?
A UCSD student. It isn’t made, endorsed or supported by UC San Diego.
Something isn’t working. What do I do?
Reload the TSS page first: TSS often answers “503” when it’s busy. If it’s still wrong, emailtridentspeeducsd@gmail.com with what you clicked and what you saw.
Questions, ideas, feedback?
Bug reports help the most. And if TridentSpeed got you into a class, that’s great to hear too.
