Is the Jungian personality test accurate?

I took the Briggs Meyer test based on Carl Jung's theory & I keep getting different results. I get INTP the most & seem to fit the description of that type the most with the exception of being good at math & being emotionally cold but I am not one to reach out to others in need & I feel comfortable expressing my emotions around my close family but that's it. I have also got INTJ & ISFJ. What am I?
