Let's suppose you have a full day, free from classes or work, and you wish to read something new from a math textbook (which is moderately paced and at your current level), reading every single definition, example, and every proof of every theorem in each page. How many pages of math theory can you absorb in one day? I have found that I can easily read a whole chapter, but the whole chapter does not really sink in, even if I read every single word. However, if I restrict myself to 10-15 pages, it all sinks in and I can absorb and remember all the content in those 10-15 pages. I'm concerned that 10-15 pages is too little. But any more, and I cannot retain it. I admit I am not a learning machine. But I want to fully, fully understand what I read, and really grasp the heart of the matter, and not just memorize definitions and results without getting a strong feel for them. So I slow down my reading intentionally. What do the others say?
