MY COSMOSXPRESS setting

when I try to go through SolidWorks Turorials, onCOSMOSXPRESS. My result FOS is different from turorials result.(Mine is 6.56102, while turorials result is 6.64).

how can I adjust it? I don't think I have changed any setting onit.

Will it create trouble when i am taking CSWP exam?
