G is for Grid-In: Grid-Ins, or Student-Produced Responses, are the very best questions on the SAT! Why is that? Grid-Ins are the only question type that has no penalty for guessing! That means you should never leave a Grid-In blank. Grid-In responses will always be numerical and never include a radical. Also, you cannot answer with a mixed number; either provide an improper fraction or a decimal. When your answer has a repeating decimal, rounding up or down is acceptable.

H is for Hypotenuse: The hypotenuse is the longest line in a right triangle, which is opposite the right angle. The other two lines are called legs. The square of the hypotenuse's length can be determined by adding the squares of the two legs = Pythagorean Theorem! a^2 + b^2 = c^2!

I is for Inequalities: An inequality is a mathematical statement in which one quantity is greater or less than another. Don't get thrown off by the >, <, ≥, or ≤ symbols -- you can solve inequalities in the same way as you would solve an equation.

J is for "Just": "Just" is one of the most dangerous words used in math classrooms! If you hear your teacher or classmate (or yourself!) say "just change it" when solving a problem, don't be afraid to ask the actual reason for a task. Why is equally important as How when learning mathematical material!

K is for Constant: That is not a mistake! The most frequently used letter when describing a constant is k. Typically a constant is an unknown real number.

L is for Linear Functions: Linear Functions are an area in which a**ebra and geometry overlap; that means that they can be solved either a**ebraically or geometrically, depending on the question. Typically, SAT questions that ask about linear functions require you to understand the formula, y = mx + b:
y = mx + b, where m and b are constants, is a linear function, and the graph of y = mx + b in the xy-plane is a line with slope m and y-intercept b.
