1. Inequality and Absolute Value Expressions

This concept made its debut in recent SATs and it’s vital to understand the technique of forming two separate equations to solve these problems. It’s a bit of a tricky area, but with practice, you can master it.


2. Trigonometry: The Complimentary Angles Rule

Trigonometry has always been a staple in the SAT, and one rule you can’t afford to miss is the complimentary angles rule. It’s a simple yet powerful concept that links the sine of one angle to the cosine of its complementary angle.


3. Systems with Infinitely Many or No Solutions

Understanding how to distinguish between systems that have infinitely many solutions and those with none is crucial. This concept is a regular feature in the SAT, and recognizing the difference can be a game-changer in your test strategy.


4. Complex Ratio Problems

Ratios have been evolving in the SAT, with more complex problems being introduced. I recommend focusing on understanding how to manipulate and apply ratios in different scenarios. It’s not just about the math; it’s about logical reasoning too.


5. Margin of Error in Word Problems

Interpreting margin of error in word problems is a skill that can earn you easy points. The key is to understand the scope of generalization – whether it’s a city, county, or school. It’s more about reading carefully than complex calculations.


6. The Discriminant for Real Solutions

The discriminant (B² - 4AC) in quadratic equations is your go-to tool for determining the number of real solutions. It’s a concept that has been consistently tested, and understanding it can be incredibly beneficial.


7. Vertex Form in Quadratic Equations

The vertex form is another area where the SAT has been focusing lately. Grasping this concept can help you easily identify the vertex of a parabola, a common question in the math section.


8. Logical Reasoning in Problem Solving

I want to emphasize the importance of logical reasoning in solving SAT problems. Often, the SAT tests your ability to think logically as much as it tests your mathematical skills. So, always look for the logical path in every problem.
