how can i study for this test and/or still ace this math class?

ive been an honor roll student getting all a's since fifth grade which is basically the beginning of getting grades in general and currently i have all a's and one b- about to become a c in this class. algebra 2 honors. my teacher literally is terrible. all she does is give us a worksheet for homework we all have no idea how to do, and then the next day we spend looking over it but not really LEARNING how to do all the problems. i have to ask my dad for help on my math homework every day and its just not doable to sit down and practice problems every. single. day. with so much other homework. i just don't know what to do. i have a logarithms, graphing logarithms, and inverses test tomorrow and so far i only completely understand basic logarithms and inverses. i don't know how im going to study. if i don't ace this test ill have a c in math and my only chance to raise it up will be to ace the midterm but that might not give me an a. im scared because i don't want to get kicked out of honors because i get a c in the class. i've never had a c as my final grade. i know that my teacher's bad because more than half our class has a c or lower. actually more than 3/4. im actually one of the top grades and more than half of the people in our class are dropping out next semester but im sticking with it if i can. i really need to ace this test tomorrow. my grade depends on it.

MY QUESTION:

~How can i study for this test so that i ace it (good tips please, preferrably from personal experience) and how can i still get an a in this class with approx. three weeks left and no extra credit available except if i get really lucky.
