: Modern preparation books often provide sample chapters in PDF format, such as the YDS/YÖKDİL Reader

Some software and apps offer a text-to-speech feature, allowing the device to read the text aloud. This can be helpful for listening to the content while doing other tasks or for improving listening comprehension.

Modern PDF readers (like Adobe Acrobat, Foxit, or Xodo) allow you to highlight unknown vocabulary, write margin notes, and flag difficult questions. This active engagement is proven to increase retention by 300% compared to passive scrolling.

Use your PDF highlight tool to mark every transition word. This is called "skeletal reading."
