On a typical rack you have "G" points and "E" points. If the deer is a 7pt meaning it has 4 "G" points on one side and 3 "G" points on the other it is a typical. It is not decided on how many points it has on either side, unless it has 10 on one side and 2 on the other. If a rack has any "E" points that is considered non-typical. See the chart that rebel hog posted and you will get a good idea of wht it is. Kickers, drop tynes are non-typical points.
