Extra Time on Brazilian College Level Exam for Students With and Without ADHD

Standardized tests such as the Scholastic Aptitude Test (SAT) and the brazilian National High School Exam (ENEM) give more time for students with Attention Deficit and Hyperactivity Disorders (ADHD) to complete the exam. The goal of this study is to find out if giving students with ADHD more time on tests actually helps them. Additionally, the research aims to find out if more time helps students without ADHD too or not, or even if it only helps students with certain traits.
