Does anyone know what exactly the Pre-event Training & Certification add-on consists of?

There are different courses to attend. I'm tempted myself. https://www.netsuitesuiteworld.com/assets/pdf/SW22%20Pre%20Event%20training%20Catalog.pdf

Thanks, this is exactly what I needed!

It's same as lcs more the most part

The benefit is that the person training you is there with you, so you get more of a classroom experience rather than self-paced
