3. Use of Calculators
The ACT and SAT differ on their use of calculator and how they go about this. On the ACT, there is 1 math section. You can use your calculator for the whole section.
On the SAT, there are 2 math sections. On one math section you will be permitted to use a calculator. On the other math section, you will not be allowed to.
If you prefer to solve questions with a calculator and are uncomfortable with mental math, you may prefer to take the ACT.
A big difference between the ACT and SAT is how the 2 exams are scored. They are scored on 2 completely different scales.

|Sections||Reading, Writing, Math, Science||Evidence-Based Reading & Writing, Math|
|Total Score||R+W+M+S / 4 = average between 1 & 36||EBRW + M = total between 400 & 1600|
|Essay Score||Analytical scoring rubric between 2-12||N/A|
