I would rank the classes in order:<p>1. Accounting - It&#x27;s the language of business. Like learning English before you become a pilot. This class helped me start asking deeper questions when meeting with business people.<p>2. Finance - Holy cow, the ability to put a value on cashflows and understand the cost of capital really opened my eyes to the big picture. I also use my Finance classes to help when deciding to take Job X or Job Y...<p>3. Strategy - My FAVORITE class of my MBA. It&#x27;s helped me when a complex situation arises--I can objectively measure the different components of the problem and look for solutions.<p>4. Economics - Really impacted me to ignore the hype of the news. &quot;CHINA WILL OVERTAKE THE US ECONOMY IN X YEARS&quot; So what, it isn&#x27;t a zero-sum game.
