This is a intensive reading technique and a note creation technique. When you read, after you finish reading, read the summary if there is any. Now question yourself what you need to get from the text. This will create a mental set by which you can comprehend more in less time. Now, start reading with the focus on getting the answers you need. Now recite what you want to commit to your long term memory. Repeat the process until you are satisfied with your performance or requirements.
