I think those of you with exams need to get yourself sorted -
unless you intend to devote your life to the breeding of tropical/marine fish and/or plants then you need to settle down and study. Its how well you pass your exams that is going to determine the rest of your lives, the sort of jobs you get and how much money you make.
(and yes I am a mother of 3 young adults, the youngest a Year 13 and yes she does get the same lecture)
