I just bought an ACT study book for the test on Februrary 12. It also came with these sparknotes sheets, that gives the general idea of the Math and reading of the test. They come with formulas and how to solve different math equations from Algebra I, Algebra II, and Geometry. The big pack of ACT booklets also come with practice tests, which i will take next weekend so that I know what the test will look like the following weekend.
