Content Update: February 2019 (Excited for Econ! ....and more!) 💸

Last month we announced that AP Microeconomics would be getting some serious updates, and that's fully evident in February's new content. If you've been eagerly awaiting new videos and exercises on topics like utility, demand, and price elasticity, this month is for you. But even if you're already an expert in those areas, we have new Art History or US Government content for you as well. There was over 80 items added total last month - check it all out below and stay tuned for the next batch! :-D
