The Unit 4 resources have been made available. We are currently reviewing them to make sure everything is there, but you should be able to find them now.
The downloadable resources for unit 4 aren't available, yet.
In order to avoid getting ahead of our production schedule and risk completing unit 4 before unit 5 is available, we do not recommend beginning to teach unit 4 before January 28th. Many of our staff are out of the office due to the Thanksgiving holiday, so I can't get an estimated date for the availability of the downloadable resources right now. However, they will definitely be available well before the end of January. I'll get you an ETA as soon as I can.
