To stay focused before an exam, maintain a regular sleep schedule, eat balanced meals, stay hydrated, and study in short, distraction-free sessions with planned breaks. Light exercise and mindfulness can also improve concentration. Nootropics such as Artvigil (armodafinil) may enhance alertness and wakefulness, especially in people with certain sleep disorders, but evidence for improving learning or exam performance in healthy individuals is limited. It can also cause side effects such as anxiety, headaches, insomnia, and increased heart rate. Use it only under medical supervision.
