Features: Item bank construction is a fundamental aspect of an examination. Building an item bank requires certain mathematical models, such as the true score model of classical test theory and the item response theory model, so that each item has objective data as parameters. This ensures that the average difficulty, difficulty distribution of individual items, and discrimination distribution of every test paper meet predetermined quality requirements before use. Item sets without mathematical models are referred to as item pools (ItemPool). The construction of the College English Test Band 4 and 6 item bank currently employs the classical test theory (CTT) mathematical model and is combined with the item response theory (IRT) mathematical model. For standardized tests, everything must be tested and supported by experimental data. This book includes ten sets of simulated tests for the College English Test Band 4 and 6, with item formats and difficulty levels identical to those of real tests. In addition to reference answers, each set of tests is accompanied by concise yet comprehensive annotations that analyze the question-setting patterns, common mistakes made by examinees, and key points to pay attention to. These annotations also explain problem-solving methods, approaches, and techniques, aiming to help examinees generalize and apply their knowledge effectively.
