<p>^Not a judgement on your kids at all, but just because a student ‘works hard’ doesn’t mean they will get the top grades available. I teach in a difficult-to-get-into program, most students are ‘good students’ yet most do not get the highest grade available. Some kids really just grasp material a lot more fluidly and easily than others, some work more effectively but less hours. I have a handful right now saying “I don’t know why I didn’t do well on the final because I really studied and thought I did well…” but they truly just did not get the material at the level necessary. </p>
