If you want to read 100 pages and more faster without losing comprehension and  think about how long does it take to read 100 pages [1]? There are some techniques to build into your routine. 

So, first of all, you can glance at chapter titles, headings, and subheadings. This primes your brain and helps you anticipate what’s coming — which makes comprehension easier and faster. Next step,  run your finger, a pen, or even your eyes deliberately across lines. This reduces backtracking (a common slowdown) and keeps your focus steady.

Instead of reading word by word, train your eyes to grab 2–4 words at a time. Over time, your eyes will naturally expand their span, helping you move quicker.
