You have two options in order to get access to a revision course pack:
1. You can buy a pack yourself, this is covered on this page.
2. You can use a voucher given to you from your teacher.
To purchase a pack yourself choose "Buy or renew a pack" from your home screen.
You will then see a list of packs that you currently have along with other available packs.
To renew a pack or purchase a new one simply select it.
Fill out the details requested and then select "Pay". The revision pack will be added to your account for the number of months you purchased.
If you are renewing a revision pack you currently own it will add the number of months you purchased to the end of your current remaining period.
