Explanation:

Reading difficult material

Reading difficult material can be a matter of concentration

or of simply organizing the challenge into steps:

Choose a moderate amount of material or a chapter to begin

Get a grasp of how the material is organized:

Scan the section for titles, headings, sub-headings, and topic sentences to get its general idea; pay attention to graphs, charts, and diagrams

If there is a summary at the end of a chapter, read it.

Check the beginning and the end for leading questions and exercises

Read first for what you do understand, and to determine difficulty.

Mark what you do not understand to review later
