Jenn,
We do have the tracks available now on teh Summit webpage under University (
http://summit.marketo.com/2015/university). While some of the sessions are introductory, we have added more sophisticated topics into the tracks to ensure they are applicable to existing Marketo users. Note the
Engage track in particular has both our new
Using Real-Time Personalization course as well as
Customizing the Look & Feel of Creative Assets, which is a developer-level course.
