blood sugar levels

So I "technically" passed my 3 hour glucose. my fasting level was a 115 and my doctor said she wants it below 95. but I passed my other three blood draws.So now I have to check my sugar 4 times a day for 2 weeks. well, just to check my levels I checked it 2 hours after dinner, as instructed, and got an 88. is this a normal blood sugar level?
