Grace Periods and Your Access to Lt

The grace period gives eligible students up to 21 days of Lt access while arranging an access code or course payment.

Who can use the grace period?

Grace periods apply where students are responsible for activating their own Lt access. If your institution covers your access, you do not need to enter a student access code.

The grace period lets you begin your coursework while you confirm your enrolment or arrange payment. Follow your course information or ask your instructor how to obtain access for your course.

When does it start?

Your grace period starts when you activate the option to enter a code or pay later. Accepting an invitation or creating an account alone does not start it.

  1. Access the correct Lt course using the instructions provided by your institution. Complete any invitation or account steps shown.
  2. When prompted to activate your access, choose the grace-period option if you are eligible. Depending on the setup, this may be labelled Enter Code Later or Pay Later - 21 Day Grace Period.
  3. Open your course and check the remaining time shown in Lt.

The period runs from activation. It is not 21 separate days of signing in. Signing out and returning later does not restart it. You can activate your paid access before the period ends.

Check how much time remains

Look for the grace-period banner on your Lt student homepage. It shows your remaining time and provides an option to enter an access code. If direct purchase is available for your course, you may also see Pay Now.

Check the banner for your remaining access period. Available payment options depend on your course.

Before the grace period ends

Activate your access before the deadline to avoid an interruption:

  • If you have an access code: select the access-code option in Lt, enter the code and follow the prompts.
  • If direct purchase is available: select Pay Now and complete the payment steps shown.
  • If you need a code or purchase instructions: check your syllabus or ask your instructor.

Once the grace period expires, you must enter a valid access code or complete an available course purchase before you can continue using the affected Lt course.
