Update Plans

I wanted to let you know what the current plans are for updates this July. I’ll make a similar post at the beginning of August.

In terms of new content, there are going to be 3 new / revised lessons by the end of this month. There will be two new lessons at the end of chapter C.5, and I think I’ve come up with a better way of explaining principal component analysis so will revise at least one of those lessons in D.2.

After those are done, I will start expanding the practice problems. This is going to be a continual process, with some problems coming in July, more in August, etc.

Finally, I’m making formula sheets which are going in a new section labeled `Before You Begin’. This currently contains the formula sheets that the CAS will give you on exam day, plus formula sheets for Section A. The Section B formula sheet should be up later this week, and I expect Section C and D to follow by the end of the month.
