Advance organizers, questions and cues

My 8^th grade science students are to going to take the Nebraska State Accountability Test (NeSA) in less than a month.  I need to review information from the last 3 years or so. I read KWL chart is great for background knowledge and advance organizers help to emphasize essential ideas. Can anyone help me to use this Marzano’s instructional strategy more effectively with students to review information that I'm sure they have totally forgotten? Any ideas are going to be greatly appreciated. Thank  you!!!
