Have you ever taken a personality test?

I took one that said I am an "ambivert"..51% outgoing, 49% INCOMING. I can be outgoing in small blips, but I neeed my loner time to recover, and I'm not at all afraid to go to a movie or dinner alone. I also took Meyers-Briggs, and I am an INFJ. Did you like your results/find them accurate? Everyone thinks I'm really extroverted, but I can also be painnnfully shy.
