S&T Pre-Internship Training Week

To all ex S&T summer analysts: I was wondering what does the training week at the outset of S&T SA programmes entail? I'm considering using that as an indicator of what pre-internship prep I should do and even regardless of that, it'd be nice to know beforehand.

I've also heard "Zoologic modules" pop up on a number of occasions in related discussions. A quick Google search didn't yield much so any info regarding this will also be much appreciated. Thanks!
