Not just that...
Even though the exam is majorly recognized by all four-year universities in the US, close to 200 institutions outside of the US also accept the ACT test scores.

Each section of the ACT exam receives a score between 1 and 36.

Your final score will be an average of the scores taken from each of them.

The Writing Section, on the other hand, is measured from 2 to 12 and does not affect your composite score.
