The Math skills required for the SAT are of a basic standard that should be within the reach of a tenth grade student. You don't need to learn up lots of new formulae but you will need to sharpen up your thinking skills.

Questions are of two main types:

Problem solving - multiple choice (5 answer choices)
Student-produced response questions ('grid-ins')
The three Math sections are organized as follows:

One section of 25 minutes containing 8 problem solving questions and 10 grid-ins
One section of 25 minutes containing 20 problem solving questions
One section of 20 minutes containing 16 problem solving questions

You will see that there are a total of 54 scored math questions on one test. [Remember that each actual SAT test contains one experimental section of 25 minutes; this section could be math, writing or critical reading. Experimental sections will not be scored... they are used for research purposes.]

Math questions on the SAT will be of different difficulty levels. Each section will start out easy, move to medium level and end with hard questions.

In any of the question types you may be tested on basic arithmetic, algebra, geometry and a few miscellaneous topics (mainly data interpretation and applied math).
