Or maybe you are too mathematically minded.
One reason that advanced statistics and probability courses are cool is that you end up learning the basic principles behind basic statistics courses. A lot of basic statistics are just "plug and chug". In this situation, take these numbers, do this, and put them into this formula. The reason for this is that most statistics jobs involve "take these numbers, do this, and plug them into this formula." DO NOT MESS WITH THE FORMULA.
It's not until you get into higher level classes where they go into why the formulas are what they are.
