These problems were prepared with reliance on fundamental topics that are traditionally covered in high school chemistry courses supplemented with six topics of advanced difficulty for the Theoretical part and one topic of advanced difficulty for the Practical part. These topics are listed under “Topics of Advanced Difficulty”, and their applications are given in the problems. In our experience each of these topics can be introduced in two to three hours. Whenever possible the relevance of the problem in the chemical sciences, and to the complex world in which we live, is given.
