Welcome to TigerSnatch!

TigerSnatch helps Princeton students with course enrollment through its Subscriptions and Trades features. With Subscriptions, students can receive an email and text message when spots open in a full course, so they can avoid repeatedly checking official Course Offerings. TigerSnatch Trades, a first-of-its-kind system at Princeton, connects students who want to switch into each other's full sections.

TigerSnatch began as a Spring '21 COS333 project at Princeton University by Shannon Heh '23, Nicholas Padmanabhan '23, and Byron Zhang '23.

Tutorial

Before you start Snatching for course spots, here’s a brief guide on how to use TigerSnatch.

Don't forget to set your phone number and change other Subscription settings on the Dashboard!

Search for courses by department, number, and/or title.

Toggle “Subscribe” switches to activate or deactivate email and text message notifications for spot openings in specific course sections.

If you're already enrolled in a full section but wish to switch into another, use Trades. From the dropdown, select and save your currently enrolled section. Then, click Find Trades to view and contact other Tigers who are enrolled in a section you want (i.e. one of your Subscriptions) and who are subscribed to your currently enrolled section.



Return to the Dashboard to check out your Subscriptions and the sections you wish to trade with other Tigers.



It's that simple! The next time a spot opens up in a subscribed section, you'll be notified immediately via email and text message. If you didn't get the spot, just resubscribe on TigerSnatch to get notified when spots open again. To unsubscribe from a section, simply toggle the section's switch off in the Dashboard. Or, if you want to stay subscribed until you manually unsubscribe, change your settings on the Dashboard!

View statistics about TigerSnatch and track your most recent Subscriptions and Trades notifications on the Activity page. Also, to learn more about improvements to TigerSnatch, check out Release Notes on the About page!



TigerSnatch Subscriptions are independent from official course waitlists. You might not be able to enroll in courses shown on TigerSnatch even if spots free up. Always check Course Offerings for course-specific enrollment and waitlist info.

Welcome to TigerSnatch!
TigerSnatch helps Princeton students with course enrollment through its Subscriptions and Trades features. With Subscriptions, students can receive an email and text message when spots open in a full course, so they can avoid repeatedly checking official Course Offerings. TigerSnatch Trades, a first-of-its-kind system at Princeton, connects students who want to switch into each other's full sections.
TigerSnatch began as a Spring '21 COS333 project at Princeton University by Shannon Heh '23, Nicholas Padmanabhan '23, and Byron Zhang '23.
Tutorial

Before you start Snatching for course spots, here’s a brief guide on how to use
TigerSnatch.


Don't forget to set your phone number and change other Subscription settings on the Dashboard!


Search for courses by department, number, and/or title.


Toggle “Subscribe” switches to activate or deactivate email and text message notifications
for spot openings in specific course sections.


If you're already enrolled in a full section but wish to switch into another, use Trades.
From the dropdown, select and save your currently enrolled section. Then, click Find
Trades to view and contact other Tigers who are enrolled in a section you want (i.e. one
of your Subscriptions) and who are subscribed to your currently enrolled section.




Return to the Dashboard to check out your Subscriptions and the sections you wish to trade
with other Tigers.




It's that simple! The next time a spot opens up in a subscribed section, you'll be
notified immediately via email and text message. If you didn't get the spot, just
resubscribe on TigerSnatch to get notified when spots open again. To unsubscribe from a
section, simply toggle the section's switch off in the Dashboard. Or, if you want to stay
subscribed until you manually unsubscribe, change your settings on the Dashboard!


View statistics about TigerSnatch and track your most recent Subscriptions and Trades
notifications on the Activity page. Also, to learn more about improvements to TigerSnatch, check out
Release Notes on the About page!



TigerSnatch Subscriptions are independent from official course waitlists. You might not be able to enroll in courses shown on TigerSnatch even if spots free up. Always check Course Offerings for course-specific enrollment and waitlist info.
