Hi,
Unfortunately sometimes nerves gets the best of us. Don’t worry, schools normally don’t care if a student takes the exam multiple times. One can still apply to the school they want to even if their score is a bit below what is being asked for. If you have the time , you should retake the exam. Regardless of if you are far, or if you are extremely close to your GMAT range, I still recommend a retake. In addition, you can always ask the school itself whether it is worth doing. Sometimes they actually help in that regard. You should check out our blog for some extra info:

If you have any other questions please feel free to ask.
