What type of resources can be useful for English language preparation?

Resources that focus specifically on English grammar and comprehension workbooks are highly beneficial for English language preparation because they are designed to improve a learner's understanding of the language's structure, rules, and usage. These workbooks typically feature exercises that allow learners to practice grammar, enhance their vocabulary, and develop reading comprehension skills. The targeted content in these resources aligns directly with the goals of mastering the English language, making them particularly effective for learners wanting to improve their proficiency.

In contrast, history textbooks, mathematics reference books, and science journals primarily focus on their respective subjects. While they may contain some written English, they do not specifically provide the structured language practice that grammar and comprehension workbooks do, thus making them less effective for dedicated English language preparation.
