I am sending you this message to say thank you for all your efforts in helping me on this long journey. You have helped me a lot. All advice and crucial knowledge that you gave me were just fantastic. I understand that your classes were useful not only for increasing my chances of getting good scores in my exams but also for improving my capacity to communicate in English using scientific medical terms. Again, thank you for your friendship and commitment to your work in helping people like me to achieve their dreams. Dr. Cesar Alves, Researcher, Philadelphia, USA.
