GMAT Strategy

Hi expert sorry if similar question has been asked before
I usually finished my 37 Q questions with extra 5-10mins on the clock
I am thinking of not submitting the final question and let the clock just tick tell last minute so I have extra few minutes to rest on top of the optional break.
I need a bit more time to rest before starting my V (my weakness)
Will this strategy affect my Q score? Because computer will record that I spend 10+ minutes on my last question (and will answering it right or wrong affect the result as well?)
Thanks a million!

youre fine.

Unless you're getting every quant question correct (which is highly unlikely due to the test's adaptive nature), I think you should use your quant time to the fullest. Do you really need an extra 5-10 minutes for your break, rather than trying to rack up a few more points in quant?

Although you'll technically be fine with your plan, I don't think that's a great approach.
