Grade forgiveness applies when students repeat the same college level course in which they earned a "D" or "F" grade. A student may not repeat the same college level or college preparatory class to improve a grade of "C" or better (State Board Rule - true at all community colleges in Florida). You may audit a course if you just want a refresher on the course content (with the exception of developmental courses). A certain limited number of approved courses are repeatable for credit without the penalty of full cost of instruction.
