Not sure the link can get you a free assessment: http://www.testsonthenet.com/DISC/disc-infoold.htm (fyi, she did not have a chance to test on this site herself, if anyone of you manage to have the free DISC assessment via this site, please let Miss Tan know. Thanks)
However, she will be trying to ‘dig’ out her old DISC & MBTI instruments (if she can find) and let us have them the next time when we see each other- next Monday.
Nevertheless, the followings are for your knowledge:

DISC

DiSC is a model of human behavior that helps to understand "why people do what they do." The dimensions of Dominance, influencing, Steadiness, and Conscientiousness make up the model and interact with other factors to describe human behavior.

Each of us has developed a distinct way of thinking, feeling and acting which becomes our behavioral style. Our unique patterns distinguish us from one another, and express our individual identities just like our thumbprint. Each DiSC style has great strengths, and potential limitations if overused.

DiSC provides individuals with valuable feedback information that will enhance personal and professional effectiveness. Become "people smart" - by learning to understand yourself and others better.The true essence of DiSC is learning about behavioral diversity and Emotional Intelligence. Individuals can learn to adapt their behavior, and move from judging those who are different from themselves to honoring, valuing and respecting others.

MBTI

The Myers-Briggs Type Indicator is a self-report questionnaire designed to make Jung's theory of psychological types understandable and useful in everyday life. MBTI results identify valuable differences between normal, healthy people, differences that can be the source of much misunderstanding and miscommunication. Taking the MBTI inventory and receiving feedback will enhance your own understanding and self-awareness. It will also help you appreciate people who differ from you. Understanding your MBTI type is self-affirming and encourages cooperation with others.
