Performance is something that will be achieved at the institute. Everyone has different abilities in doing a task. Placement of an office position does not always result in satisfactory performance. Giving an assignment to people who are not qualified in their field will cause problems in the future. This problem arises from the inability of the person to overcome and complete the assignment. Position balancing is a terrible thing facing every institution. Many of the criteria that should be assessed for a person can be put in a specific position. Manual calculations will hinder the accuracy of employee placement in the company. The Gale-Shapley algorithm can solve this problem well by the expected criteria in a particular position. This algorithm determines the position of work based on the desire of the institution and the ability of the worker. The interchange between employees will occur if the weight changes. The optimal person will fill each job position in the field of work. Stable Matching will be implemented, and the institution will have qualified employees.

Passing the national examination is the main target for all students who are going to finish their high school. There are a lot of ways to get it, such as: taking course, get private learning, and do try out examination. Try out examination is a mechanism that is used as an exercise for students before carrying out the actual examination. But there are limitations of time, place, and money in having it. Not all students have a change to do it in a specified time or place, or have money to take it. In order to overcome these problems, we offer an application that could be used anytime and anyplace in low cost as long as they have internet connection with them. The application would be based on web and could be repeated whenever they want. Due it could be taken repeatedly, the questions should not be same every time they would do it. That’s why we propose linear congruent method as this method could produce random number. Practical advantages from these methods are: speed, ease of implementation, and availability of portable codes, parameters, and test results.
