Once you're enrolled in a program, its exercises and series unlock for you.

## The active period

A program has a **start date** and an **end date**:

- Before the start date, the content is not yet available.
- Between the dates, the program's exercises and series are unlocked — **even if
  you have no subscription**.
- After the end date, that content locks again.

## What's included

Only the exercises and series that the instructor added to **that program**. It
does not unlock the rest of the library.

Program exercises show a **Program** badge in the Exercise tab so you can tell
them apart.

## Finding your programs

Program-linked content appears alongside the normal library. If you also have an
NFC session card, enrolling in a program automatically links it to your card for
class check-in.

## Classes in the program

The program's live classes can be attended without a subscription or session
card — see [Checking in to program classes](check-in-to-program-classes.md).

## Leaving / being removed

If an instructor removes you from a program, or the program ends, the unlocked
content is no longer accessible unless you have a subscription or trial.
