ACT Science

The Science Reasoning portion consists of 40 questions to be answered in 35 minutes. Students will read 4-5 passages and answer reasoning questions based on the passages.

Chad Cargill teaches in his workshops that this section is not about what is right, but about what is not right. The students will look for the most correct answer by eliminating the answers that are incorrect.
