  21. 21. Reflections <br />Wallace : I feel that this course has been an extremely enriching one. I have learnt much in the duration of the course. My team mates and I had several disagreements but ultimately, we got through. I feel that we have come a long way since the first day of the course, where we had no idea of where we were heading, what we were doing, and even why were we there. I was suffering from constant fatigue during the course. Much work had to be done on an extremely tight schedule. Nevertheless, my team mates and I had acquired a sense of accomplishment at the end of the day- it paid off. I hope that I will have the chance to attend another similar course in the near future. <br />
  22. 22. Reflections<br />Alex: I have learnt a very important lesson through this sabbatical. Through questioning we can tell that we, students of Singapore, are quite useless when it comes to something not in our textbooks. I have learnt to broaden my knowledge so that this knowledge can be used for all purposes and not just for structured examinations. This is the biggest take back from this sabbatical as this is a skill that many of us lack and is very vital for us to think critically in the future. <br />
