Starting to become worried about the praxis

I heard it’s really hard. The history one is suppose to be the hardest but math one must be hard. To my knowledge is contains the calculus' and all of the higher leveled math courses. I'm taking it next semester but I don’t know if I’m ready just yet. Luckily I still have a few months before the test to get ready. Some of my classmates are taking it this summer so they should tell me how it goes and hopefully give me positive feedback.
