Unfortunately, this course was not taught very well. The terms were not clearly defined, and in the final course I struggled to pass because I didn't know which term given was the one they wanted me to click. Here are two examples. She defines the term "Measurable" in a smart goal as something that has evidence to prove whether it [the campaign] was was successful or not. Then a few seconds later, she gives a second definition: "a measurable goal that contains a number you can track and measure along the way." Two different definitions for the same term, "measurable." When I took the quiz, sure enough they asked for a definition of "measurable," and both of these answers were listed as options. I selected "It has evidence to prove whether it was successful or not," the first and foremost definition she gave. I was "incorrect," and it cost me the test. Again. I had to take it 4 times because of this kind of nonsense. Another example: In the course she defines the equation for calculating conversion rate as "The Number of conversions / number of clicks." However, as she says this, the accompanying text reads "Number of conversions / Total emails sent." Literally two different definitions. I thought the second one made much more sense, but of course when I selected it during the final quiz I was once again "incorrect" and it cost me the quiz. This was very, very frustrating. I hope that you guys fix this course.
