Hi, it is not good to take tablet for improving concentration. I understand you want to focus on your studies. It is important to identify what is causing you to get distracted. You can make a time table and provide a time schedule for each subject. I understand the thought of studying for long hours can be stressful. To help improve concentration 1. You can make a time table in a way that you give yourself breaks in between to relax your mind. 2. You can also create a comfortable place to study by decorating your room with nice showpiece. You can consult a psychologist who will help and guide you ways to improve concentration based on your daily routine and lifestyle. Counseling sessions will help you.

It is not advisable that you should take any tablet or medicine to increase your concentration and focus. You may not be interested in your studies or because of some factors you get distracted.
