A 12 point spread between the different tests doesn't seem unreasonable to me. 128 and 140 are both quite a bit above average. I tested at 135 in third grade, 140 in 5th grade and 140 as an adult.

Your iq DOES NOT change as you grow older, it remains constant. If you are ten and get a good score it is not going to improve!!!
