Please help. I combine work and school just to help cater for myself and have cash to for study needs. Cos of work, I sometimes miss lectures but I'm always available for tests and exams. Work have been stressful lately, I missed the last one week of lecture. I collected a friends note to photocopy. The subject is statistics. Long story short, examples lecturer gave contradicts workings in other textbooks I've studied which will arrive at different answers. Should I solve based on lecturers pattern or use the one I feel is right? I've argued with course mates we agreed to meet the man but I feel it's going to make him think I know more than he does. Please what should I do? I have the exams this afternoon

For the sake of A, Do your lecturer own.
