My results:
The Investigator

Independent, innovative, and inventive, they can also become preoccupied with their thoughts and imaginary constructs. They become detached, yet high-strung and intense.

The Achiever
Type Three => 5 out of 8
The adaptable, success-oriented type. Threes are self-assured, attractive, and charming. Ambitious, competent, and energetic, they can also be status-conscious and highly driven for advancement. They are diplomatic and poised, but can also be overly concerned with their image and what others think of them. They typically have problems with workaholism and competitiveness. At their Best:: self-accepting, authentic, everything they seem to be—role models who inspire others.
The Individualist

The introspective, romantic type. Fours are self-aware, sensitive, and reserved. They are emotionally honest, creative, and personal, but can also be moody and self-conscious. Withholding themselves from others due to feeling vulnerable and defective, they can also feel disdainful and exempt from ordinary ways of living.
