EXPLORE is the first part of a testing system that goes on to include PLAN and the ACT.
Typically, students take EXPLORE in the 8th or 9th grade, PLAN as 10th graders, and the ACT as juniors or seniors.
All three test you in English, math, reading, and science. However, the material tested in each program gets more difficult.
This is why the top scores are different.
|EXPLORE||8 and 9||1 to 25|
|PLAN||10||1 to 32|
|ACT||11 and 12||1 to 36|
