I am currently in the process of updating some things for the Spring 2017 sitting.

1. All the lessons are being reviewed to shorten or remove unnecessary calculator demonstrations.

2. All the review lessons have been moved to the end of the lessons page, after the “What to do after you have finished the lessons”.

3. Some typos and small errors are being corrected.

So, don’t worry if you are noticing many lessons being marked as “new” when you visit the lessons page – these lessons are not new, and have only been either shifted in location or mildly updated.
