NSE5 Secure Wireless Lan exam resources?

What resources did you use to pass this exam? I went through the free course on fortinet institute and felt like I understood most things. I have my CWNA so i know the basics of wifi. But the finer details such as memorizing specific CLI commands have me questioning if I’m ready or not. Does the exam test on tiny details like this or is it more broad? I scored 90% on the sample questions but it’s only 8 questions so i know it doesn’t mean much. Have any of you found any good practice tests to gauge your readiness?
