One technique that the form three students could use to quickly and easily get the central idea of the textbook is called skimming. Skimming involves quickly glancing over the text, reading headings, subheadings, and the first and last sentences of each paragraph. This technique allows students to get a general understanding of the main topics and ideas presented in the textbook without reading every word.
