in 1998,Paper-based TOEFL was changed into Computer-based test which people take test using computer.CBT has four sections such as reading,listening,writing and sentence structure.CBT score ranges between 0-300.
Finally in 2005,The new design of TOEFL test is created which is called IBT(internet-based test).Although CBT and PBT were well standardized tests,students who took CBT with high scores could not speak in English well.Therefore ETS designed IBT including reading,writing,listening and speaking sections.IBT score ranges between 0-120.
