Regents Review
Some Suggestions Read the question twice. This is NOT a race. Read the info regarding the question. LOOK at everything in the diagrams. Do NOT easily (quickly) make assumptions. Think of your answer before you read the choices Read ALL the choices. Read each choice to the end of the sentence. Be aware of the possibility of trickery!
