Maybe you have the genetics in the family that has smaller boobs. Same thing happend to me when I was your age. I am now 24 and finally have a c cup. Don't worry about it. Bigger boobs just mean more back ache, literally. You sound like a late bloomer like I was. Be patient! You'll get more than you bargained for! LOL
A person who wears a size 36 bra is more than likely just beginning to grow breasts. A 36A is for breast which have formed but are still small.

The cup volume is exactly the same; the cup of the 36A would fit the 28DD breasts, though the band size would be much too big, of course. However, proportionally the 28DD breasts may look bigger because the person would have a narrower back. The breasts themselves are the same size in both cases, just on different frames. So I guess which size is 'bigger' depends on how you want to measure it: visually, the 28DDs would probably look bigger because they're on a smaller frame.
The GCF is 4a.
The GCF is 9a.
81a^2+36a+4 a = -2/9

Nothing.
Yes being a 36a is perfectly normal especially if you are an early developer. In middle school, I was a 36B.
