School Based Assesments: Basically worth 20% of your CXC or GSCE exam depending on where you're from. A chance to get at least a C or a 2 on your exam if you fail it. Pretty much a waste of time
Teacher: Get your SBA's done by tomorrow or else you'll fail your final exams and have absolutely no future.
