“I am no good at ACT Science,” my students tell me frequently. Too frequently, in fact, to be a coincidence. The first problem with this statement is the fixed mindset. Someone with a growth mindset would offer, “I am no good at the ACT Science yet.” The second problem with this statement may have less to do about Science and more to do about stamina. Stamina may be the main challenge on the ACT since the Science section is the last section of the test. After hours of testing, tackling another section of critical and logical thinking may just be too much for students to handle.
