BIEM's main statistics course has a wide range of topics. Hypothesis testing is the most significant part of the course. Ample resources such as TA questions and past exam questions make studying easier.  However, as in many other statistics courses, having too many formulas to know and Bocconi not allowing formula sheets in the exams challenge students.  That is why I try to intuitively show which formula used where and how to transform formulas in order to decrease the number of formulas to know.
