Cambridge E-checkpoints? Eh?

[ZachCharge]

G'day,

Was working out of a friends Cambridge Checkpoints 2010 CAS book today and couldn't help but notice a delight advertised on the back page, e-checkpoints "(corny advertising) is now available in electronic format". However, looking at http://www.cambridge.edu.au/education/companion/checkpoints/books/mathm_cas.html, and through google searching...I can't seem to find the so called e-book...

Does anyone know how to acquire it...or if it exists?

Thanks

I think they are the " interactive quizzes ", and of course, you would need to have the Checkpoints book and enter the username (specified on the webpage) and password, which is the "The third word of Question 85  on page 99". If you already knew this and I'm not even answering your question, sorry about that!
