Preparation for NSE 4 Pearson Vue Exam

The company I work for is currently going through the Fortinet Partner program and as such, many of us are being told to go as far as we can with the training.

I got to admit, im used to working for companies that want me to fund my own training, so im doing my best to take advantage of the free resources.

Ive gone through the NSE 1-3 and now feel comfortable that I can talk about Fortinet services and functionality with customers, but I do lack the experience with the Web UI and CLI, so the NSE 4 program in the partner portal has definatley been an eye opener.

Question is... Whenever I do these "practice questions" in each module, they seem to throw curve balls. It was the same within the NSE 1-3 series. Asking questions that are not covered within the training, or covered "by proxy". By that I mean you will be given a chart for a Gartner report and in tiny characters down the bottom will list that it was for the 1500 in 2014, but the host made no reference to it.

I really do wish to take the exam, but im curious as to how well prepared the Fortinets Partner Portal Powerpoint slides leave you? Ive been working through the Cookbook videos and have a book on Fortinets UTM en route too.
