if you're indecisive, or anxious about answering something wrong, you can't go back to answer differently unless you reset the test so be cautious and safe. you'll get what you want eventually.
the result of the test got me was unsure and made me choose what would fit best for me instead of actually pointing out one that could not be me which is nice, I liked that. though it might make people indecisive if that happen with someone who is indecisive, which isn't much of a problem for me specifically.
