The VID1b website has all the necessary tutorials and tests. It’s still got a few glitches, so please email me if you find any. There are a series of tutorials for unit 3 that will remain under construction for some – but those tutorials will be optional and won’t be included in any tests. My students piloted all the materials this semester and had no problems. The final exam works as expected, and is producing the same kind of high student growth scores as the VID1a final exam.
