In every section on the ACT, there are some questions that are more difficult than the others. Science is no different. However, unlike the math section, where the questions progress from easy to hard in a linear fashion, each of the 7 passages tends to have 1-2 hard questions that can appear at any point in the passage (though they tend to be the last questions of the passage).
These problems may seem challenging at first glance, but they're really just slightly more challenging than the others if you use the right ACT Science strategies and tips that we'll be covering in this guide.
