Based on Simon’s teaching that planning is the most important part of writing.

Another critical, yet understated, value of the "IELTS Simon PDF" is its efficiency. Official IELTS books are expensive, and full-length practice tests can be exhausting. The PDF format allows for targeted, micro-learning. A student waiting for a bus can review a single page on "how to write a topic sentence" or memorize a handful of "native-speaker collocations" from Simon’s lists. Because the content is distilled from years of daily blog posts, it is free of filler. This lean, high-density format is ideal for self-studying students, particularly those in developing countries who may lack access to live tutors or expensive courses. It democratizes high-quality preparation, placing an examiner’s insights directly into the hands of anyone with a smartphone or a printout.

For speaking and writing, Simon promotes a clear development pattern: Idea → Explanation → Example .
