How old are you? We change a lot in our lives, obviously, and for that it can vary. Also, your mood when taking the test can make a big difference to, or just where you are at in life. Then again, your letters may just be very close. You can be a strong introvert and have a strong J but then be neutral in the N/S. Myself and Sarah both have very closely swapped letters too. A lot of tests don’t give that much leeway though either, in my opinion, most of them are pretty black and white and I think that it depends on the situation for a lot of things - so that can also be a problem. Sometimes you don’t really need the actual test to determine what you are, just research the types a bit and see which one fits you best. ~Taylor
