Study for Fortinet NSE4

Hey guys,

I have already worked my way through NSE1-3. I have a pair of FGT200E at work that have been decommissioned and aren't being used for anything. I also have a 60F at home paired to a fortiswitch and FortiAP. Between the two, do you think I would be able to get the hands on experience needed to pass NSE4 without paying for their labs?
