Many schools have started grouping students by levels and requiring them to take a level test first. While this seems to work pretty well at language schools it may backfire in schools and universities, especially when English is a required course.Although you would think that people would try their best at level testing, some students deliberately choose the wrong answer so that they're put in a lower level. The idea behind this is that they can get an easy A. Some schools are starting to realize this and are using official tests, such as the Korean SATs, IELTS, or TOEFL, to group students. If your school does so level testing make sure to gauge students' levels the first few weeks of class and ask your director to move students out of your class if their level is too high.
