I think you had to purchase the web app for an additional fee back then, to be grandfathered for life.

Possible workaround: downgrade to an older version and disable auto-update?

Great read, thanks!

I believe there's a more recent version of this document available here: http://statistics.zone

To add another point, my A-Level teacher always said anything the calculator can do, you can do, and just as fast.

And then she chose a question from the book, had one of us start typing, and she started at the board solving the same thing.

She finished first. Not by much, and obviously the calculator is the faster choice more often, but she finished first.
