In conclusion, the 27th Tri-U was an interesting journey filled with lots of hardwork, dedication, sweat and tears which was sweetened by the formation of new friendships, learning new culture and exchanging ideas with students from all over the world. It definitely wasn't an easy task but the experience and knowledge gained from this was worth every long day and night spent in preparing for this event. The constant support from all the professors and teachers to help practice our speeches, suggest better ways to improve our research and presentations, and to stay determined was a crucial part in helping us do as well as we all did. We advice the rest of the OECians to not fear the journey and the hardwork but to enjoy every moment of it and to openly accept the knowledge and experience provided through this.
