1、Science reasoning testL Summary: 7 passages with 5-7 questions each; 35 Minutes 40 questions, 5 minutes per passage.IL Structure & solving method:1. Charts and Graphs-3 charts and graphs with 5 questions each; test the ability to understand and interpret the information thats presented.Scan the pass

2、agefocus on the chartsskip the introduction until u get into trouble doing questionsLook at the variables and units;Identify the question typeGuesstimate2. Experiments-18 questions, 3 passages; test the procedures in each experiment and interpret them; (skim the experiments, write down key words (st

Spend the first minute of the test determining which passages will be hardest for u-leave them until last;3. Unnecessary to know any science well, just need to be able to read passages about science topic.4. Use the process of elimination and guesstimation to eliminate incorrect ansers.
