Practice Makes Perfect!...hopefully..

So i just got done practicing my math like crazy for the past 3 hours or so. I had been struggling a little in class so I decided I'd go through my book and do all of the exercise sets for each section. I did all the odd numbers that way I could check the answers in the back to know if I'm doing them right. I am not finished with all of tye sections, but I have done pretty good on the sections that I did do. My instructor keeps telling us that grades take a dive after Chapter 2, which has me all worried. You would think your instructor would be positive, but she keeps saying it like she expects us all to fail this next test. But I hope all of my practice pays off. I am not as good in math as I would like to be, so I have to work a little harder.
