Yes! There's no expiration date or time limit, so you can book a slot whenever you're ready. You can also reschedule as often as you like, as long as it's not within 48 hours of your start time.

You can do this yourself using the "Cancel" or "Change your slot" buttons near the bottom of your confirmation email from [email protected]. A couple of things to keep in mind:
1. Exams can't be cancelled for a refund or rescheduled within 48 hours of the start time.
2. Joining more than 10 minutes after your start time counts as a no-show, and you'll need to reschedule at full cost. We recommend joining at least 15 minutes early for your ID check and room scan.

We don't currently offer public discount codes. If you're a LangChain customer or partner, check with your account team or partner contact, as codes are sometimes available.

You'll receive two invites: one for the proctored exam itself, and one to a dedicated LangSmith organization, sent roughly two hours before your start time. If either hasn't arrived by two hours before your exam, file a support ticket at https://certification.talview.com/support/home

Within 72 hours of your exam ending. If you pass, your certificate will arrive by email from Accredible. If not, you'll get an email with more information on booking a resit.

Every exam purchase comes with one free resit. To use it:
1. File a support ticket at https://certification.talview.com/support/home to request your resit code. They'll check your eligibility and send it over.
2. Book your resit through the same portal you used for your first attempt.
You can resit as many times as you like. Attempts beyond your free resit require paying the full exam fee again, and any discount or partner codes you're eligible for still apply.
Just a heads up: last-minute cancellations and late joins don't qualify for an additional free resit.

Sorry about that! File a support ticket at https://certification.talview.com/support/home and the Talview team will look into it. If warranted, they'll provide a free resit.
To avoid issues on the day, check your machine against Talview's system requirements and make sure your network connection is stable: https://certification.talview.com/support/solutions/articles/11000130864-pre-requisites-for-online-test
Sessions ended by a connection problem on your side aren't eligible for a refund.

We'd love to hear it! Email [email protected] with any thoughts on the questions or other parts of the exam.
