i'm having trouble with statistics concepts, problems, reading, trouble, question

Spongebob

meaning i'm doing the reading, and the problems, but have a hard time remembering all formulas. certain parts i'm even having trouble doing the formulas...it's all quite demoralizing! the question is, is it worth paying 1k for a class, or should i wing it, and hope that i excel at all other sections?

(i've done the other quant parts fine- so i'm not sure if statistics just bores me or if i really just don't grasp the concepts!)
