Use of Algorithm Linear Congruential Generator (LCG) on the TOEFL Test Application

Abstract

English as one of the languages most used by the world's population to communicate. The English language proficiency testing model for one of them is the TOEFL (Test of English as Foreign Language). TOEFL is intended as a measuring tool or evaluation of a person's ability to understand English. The use of internet technology advances in developing TOEFL learning media can provide other alternatives in studying the TOEFL. The existence of this website is expected to provide various facilities for the public, especially internet users in studying the TOEFL, so that the TOEFL is no longer an obstacle and can encourage someone's interest in learning English. The web-based TOEFL application system can provide all types of information needed as well as the process of listing examinees, recapitating participant data and printing certificates in a structured manner. The method used in this application to scramble the problem is the Linear Congruential Generator (LCG) method which can produce a series of pseudo random numbers based on several adjusted repetitions.
