Must one obey one's mother by going to school despite the prevalence of violence and hatred in the teaching there?

You must obey your mother by going to school, because she aims for your benefit and fears that you will lose your educational opportunity and not obtain a certificate that qualifies you for work. The corruptions found in schools are tolerated to achieve these benefits, while striving to move to a school with fewer corruptions or complaining to officials to remove those corruptions.
