Selection test is one option for students to continue their study in university. Since the competition is tight, both students and teachers need to prepare better. One alternative way is through try out test. For every try out test, students and teachers are supposed to evaluate, recap, and map the result to find out all the strong and weak subject of the students. However, this is difficult if done manually. This research attempt to help students and teachers by developing a tag-based online system that can help the recap and mapping process. All the test result can be stored, recapped, and mapped by the system. In addition, the system can group all questions with similar tags so that students and teachers know their strong and weak subject. With these information, a better strategy for learning or facing the next try out test can be made. With better strategy, hopefully the student can learn better, achieve higher scores, and enrolled to the chosen university
