Rote learning is one way to pass examinations, but really understanding the subject is even better. Most textbooks are limited to presenting facts without helping the reader review and practice. This workbook fills the gap with more than 1,000 sample examination questions from general, inorganic and organic chemistry. With it, students can practice and deepen what they have learned from textbooks. The problems can be solved without aids, and solutions are provided with detailed explanations. The workbook enjoys great popularity after helping countless students study successfully.
