At the end of each exam, you are given VCE Maths Methods Formula sheets with the key formulas you may need to use in the exam. They're pretty much the same thing every year, however, still has some useful stuff on it.
The latest VCE Maths Methods formula sheet is below:

Go through this sheet and make sure you have an understanding of each of the topic (though it maybe in a slightly different notation than you were taught or are used to).
The topics that are covered on the VCE Maths Methods Formula Sheet are as follows:
Mensuration
A brief outline of the area and volume of some of a few common shapes.
Calculus
The methods of differentiation and integration for main types of problems. It includes the basic formulas of the chain rule, product rule and quotient rule.
Probability
The first part is a summary of the Year 7 to 10 probability. It includes conditional events, mean and the formulas for variance.
Then Discrete Random Variables and Continuous Random Variables, the two categories that VCE Methods focuses on. It also has two columns with the formulas for mean and variance of either Discrete and Continuous Probability
Sample Proportions
The basic formulas used in the Statistics topic, which was introduced in 2016 and is basically a part of probability. It covers population proportion, mean, standard deviation and the approximate confidence interval.
