From last version, PPC Classroom 2.0, I've learned a lot of things there.
I learned how to setup a lot of campaigns in very short amount of time.
The course guide you through from start to end.
Keyword research, cleaning your keyword list, grouping keywords, creating campaigns.
It will cover how to use combination of spreadsheet (Excel) + Adwords Editor to create hundreds of campaigns easily and fast.

Yes, you will need a lot of campaigns and adgroups as we will try to go very very specific on the search terms and the ads writing to get maximum ROI.

I don't know what will come in PPC Classroom 3.0 as it hasn't launch yet.
