What topic are you on right? What have you been struggling on the most? Target those areas, and practice. Is it hard for you to understand the material? Or is the problem that you can't apply the methods?
Use all the resources you have. Go to extra help with your teacher, work on more problems in your textbook, maybe even buy a review book for help.
And if you like spoken lessons, try out Patrick jmt or Khan Academy (google them). They give cogent and concise explanations about lots of things you might need help on. They helped me immensely when I needed it.
Also, don't be so quick to jump to a tutor. Try figuring it out yourself first. It will be much more rewarding and will build confidence in yourself, because you figured it out without needing help.
But definitely ask your teacher for help, and use the resources I mentioned.
