A1c: The 6.5 is not a sugar level but reflects how well your blood sugar is being controlled. It is best known as a1c which reflects uptake of sugar on your red blood cells. 6.5 is an ok number but don't get higher.

not necessarily: Your glu after a meal varies with what you ate, how fast, the speed of your GI tract, etc. It is hard to precisely say whether your post meal glu are too high. If you are testing your sugars because you have diabetes, or are worried about diabetes, best to check fasting and pre-meal, and follow your a1c. Normal fasting glu is 100 or less. Diabetes is 126 or more. "impaired" is in between.
