This program is an interactive multimedia chemistry tutor that tests students as they learn. It can teach students about elements, compounds, mixtures, atomic structure, ionic and covalent bonding, bond energies, and more. Skills are taught through familiar examples that help reinforce general chemical knowledge. This program was written by a teacher for use in schools, but it is an excellent personal tutor for anyone beginning to study chemistry. Version 1.5 includes improved graphics, visual indication of correct and wrong answers, and minor bug fixes.
