Being able to study in one of the best universities in the country, such as UGM, of course, is a great feeling for most of the high school graduates. The same was what I have ever dreamed when I was in the last year of my secondary education. And luck was going with me, when I passed the exam through PBUD scheme and being admitted to Gadjah Mada University, Faculty of Mathematics Natural Sciences, Department of Mathematics, with the concentration in Computer Science. I can not describe in writing how enthusiastic, happy, nervous, impatient of it when I immediately entered a new period of my learning journey. Yes, the combination of feelings that can not be described in words.
