Babee Girl... I remember my Quant classes in my business degree and would cringe!!! In the end after writing my FINAL quant exam and (that was also my final final exam for the degree) I hoped and prayed I would NEVER EVER have to use any of that mess in my job.. so far so good!! It was a stupid class that made you head almost blow up from thinking of all the "what ifs" and best case scenarios.... I never want to see another Decision Tree in my life again!! ahhhh but saying that.... you will be fine!!! practice practice practice!!!
