<p>Yes, unless you are on the debating scientists section, skip the introductory material and go straight to the questions/graphs. You may be spending too much of your time reading than actually answering questions. You only have FIVE minutes per section, not really enough time to read and comprehend everything. </p>
<p>Just try and follow this general approach- first make a quick glance to the graphs and note the relationships between the variables (oh, when these numbers increase/decrease then the numbers in the other column increase/decrease); then read the questions, identify which graphs they require you to read, and answer the question accordingly. </p>
<p>On the debating scientists section, just read each perspective very quickly, making notes to the side that summarize what his opinion was (believes/doesn’t believe in global warming; says it’s part of Earth’s natural cycle/ it’s due to the increase in gas emissions and the greenhouse effect, etc.), and then answer the questions.</p>
<p>Skim through the passages and underline key words (variables, what they’re looking for, etc) then skim through the graphs and spend the majority of your time on the questions. I did this and completed the science with 2 minutes left to check work.</p>
<p>There are 8 videos on YouTube by SuperMagnet Man (I kid you not) under title ACT Test Prep-Science. They are great. They specifically address the main problem with the ACT science section and that is timing. I always ran out of time during practice tests. I used this guys system and increased my science score from a 24 (1st test) to 32 (2nd test). This changed my ACT from 32 to 34. It really worked.</p>
