Goal 2- Reading: I will read the material until I can comprehend and learned what I need to know. * While reading I will highlight, underline, and margin write by important facts that will help me when I go back to study. * For example in Soc 101 I have to read two chapter each week for homework. So while reading my textbook I will highlight import facts such as terms and statistics. Also margin write so I summarize that section and makes sense to me. I will do this on Monday at around 6pm and my room, to succeed int his class.
