second of all. My *** 2 or 3 times. If its for an educational experiment you should do that at least 10 times, if in research you should do more. In your situation if you are lucky and the last user of the beaker washed it thoroughly, or your smart enough to do it your self you'll be from 0.5% to 2% off and that could be the difference from not so bad done to a failed lab-work in some places.
This is the exact solution they need - they calculated how much solute to use and how much solvent they would require. 'Standard solution' is just a way of saying that a sol'n has been prepared in a specific way to a certain standard, not that all sol'ns are of the same volume or concentration.

@guitar22xkl yes but how do you think they prepare it?
