This will increase the difference between the haves and the have-nots. Students with parents who care about education will make sure they do good work. These students will be more likely to develop good study habits that they will need later in life. Students whose parents don't care will make use of the lenient system and will not learn good study habits. When they get to a school or university that doesn't do soft grading, they will be in for a rude awakening.
