If, after joining the Advanced Course, you decide to upgrade to the Pro level, you can do that at any time during your Advanced Course access.
When upgrading you then get 12 months of Pro access from the date of the upgrade.
This means that if you decide to upgrade after, say 11 months, you then get 12 months of Pro access.
The upgrade investment will be a flat rate equal to the difference between the Advanced and Pro Level investments.
Just contact us to request an upgrade.
