The most important aspect of reading is understanding,not speed. For me to complete an assignment is not as important as me actually remembering what i have read in a passage. As I read identify and focus on the key material I will need to remember later. Its not good to try and memorize everything that has been read. Another techniques is taking small breaks in between reading. This can help with distraction,calls and helping with completing house work. If i sit and read for four hours i may retain useful information but at some point everything want be retained. Its good to give your brain a break. Lastly its good to write while reading. Making outlines of what I've read or just writing down key words that focus on the topic help too.
