Study Guide PDF NSE4

Hello,

My company is Partner with Fortinet, and i heard that we had access to a Study Guide PDF for NSE4.

Where could I find it ? I'm looking for it in the Training portal but I don't seem to find it, could somebody point it out for me ?

And did somebody already used it ? How did you find it ? I'm chosing to go with this to spare some time but if necessary I can watch the free videos.

Thanks!
