This post provides a clear and practical breakdown of demand analysis fundamentals. I especially appreciated how you explained the methods in a way that's both accessible and robust. Interestingly, I recently needed someone to do my Mathematics exam for me, and reflecting on concepts like market demand helped me draw parallels between academic reasoning and economic analysis. That realization led me to explore some online exam helper tools, which turned out to be surprisingly helpful and confidence-boosting during a challenging study period.
