It depends on whether your membership has already ended or you've cancelled, but you're still within your current paid period.
If your membership hasn't ended yet
If you've cancelled but your current period hasn't finished, you can reactivate your membership here.
You will retain access and progress in any courses you have added and will be billed at the end of your membership term. This is simply turning the renewal back on.
If your membership has already ended
Once your membership access has ended, there's no separate "reactivate" step. Rejoining works the same way as joining for the first time. See here to get started again.
Does your progress carry over?
Only if you have reactivated your membership. If a payment is missed or a cancelled membership passes its initial payment date, you will lose your progress on courses you have started.
