The reason for these bad grades are: not enough patience, authority, tolerance or the ability of teaching. I've gotten the lowest grades in physics, I don't know exactly why, maybe it's because that subject doesn't suit me naturally or maybe it's because of the professor. It is most likely to be the second thing. However, professors shouldn't differenciate pupils by dividing or valuing them, especially not damaging them with grades. Some professors think that they are "above all" and they don't understand what kind of role they have in particular. Professors should change as time passes, they have to be liberal and modern and every day they should make progress concerning their teaching abilities.
