The March SAT is just around the corner, and whether you've been preparing for months or are just getting started, knowing what to expect can make a big difference! Based on my experience, here are my top eight predictions for what you’ll see on the March SAT—and how to tackle them!

🔮 Prediction 1. System of Equations with Variables in the Answer Choices
Expect a system of equations problem where the answers include variables like R and S. The best approach? Use Desmos! If the equations overlap completely (one line sits directly on top of the other), type in the answer choices as coordinate pairs and check which one stays on the line when you adjust the slider. Avoid using x- and y-intercepts to test answers since multiple choices might seem correct. Desmos will give you a clear and definitive solution.
🔮 Prediction 2. Vertex Form of a Quadratic Equation
A common question type involves writing a quadratic equation in vertex form. If given a word problem about a real-world scenario—like a seal diving underwater—you’ll likely need to identify the vertex (the lowest or highest point) and plug it into the vertex form equation: y = a(x - 6)^2 + 302.4. If the problem provides another point on the graph, plug it in to solve for (a) and complete the equation.
🔮 Prediction 3. Consecutive Odd Integers
These problems can trip people up if they’re not set up correctly. If you’re given four consecutive odd integers, represent them as ( x, x+2, x+4, x+6 ). Pay attention to the wording—if it asks for the product, sum, or a relationship between them, translate it into an algebraic equation and solve carefully. Misinterpreting these problems is one of the biggest reasons students get them wrong.
🔮 Prediction 4. Unit Conversions
Expect a problem involving converting square feet to square meters or hours to minutes. The key is squaring the conversion factor before using it. For example, if 1 meter = 3.28 feet, then 1 square meter = ( (3.28)^2 ) square feet. Set up your conversion using dimensional analysis, cancel out the units, and solve. Keeping track of units is just as important as the math itself.
🔮 Prediction 5. Nonlinear Regression in Desmos
The SAT often includes a question requiring you to use regression in Desmos. When given a table of values, enter them as a table in Desmos and use a regression equation. Instead of f(x), use (y). Desmos doesn’t recognize function notation in regressions. If asked for the y-intercept, make sure you’re looking at the right function—sometimes the question asks about one function while displaying a different graph.
🔮 Prediction 6. Tricky Linear Function Questions
These appear on almost every test. A classic example is a rental cost question where the first day has a different price than additional days. If a carpet cleaner costs $52 for the first day and $26 for each extra day, the function is: 52 + 26(d - 1), since the first day is already covered by the $52. Watch for these details in linear function problems.
🔮 Prediction 7. Quadratic Equations and Real Solutions
You might see a quadratic problem asking how many real solutions exist. If given an equation with a constant term, graph it in Desmos and use a slider for the constant. Adjust the slider until the graph no longer touches the x-axis. The smallest value where the parabola no longer intersects the x-axis is your answer. This visual approach is much faster than calculating the discriminant manually.
🔮 Prediction 8. Factoring a Quadratic Expression
This is a hot topic right now. If given a factor like ( x + 2B ), identify the second factor by checking the leading coefficient and constant term in the answer choices. Test each one to ensure the middle term results in a whole number for B. If the value of B isn’t an integer, that answer choice is incorrect.
✨ Bonus: Get Extra Practice on the Go
If you want extra practice before test day, check out Preptly. It’s our mobile SAT prep app designed for students who want to squeeze in high-quality practice in short bursts. With over 1,000 practice questions that mimic the real SAT, it’s perfect for daily review without feeling overwhelming.
💡 Bottom Line
The March SAT will test a mix of skills, but the best way to prepare is to familiarize yourself with the types of questions that appear most often. Work through similar problems, practice using Desmos, and get comfortable with key concepts like unit conversions and quadratic equations. The more you expose yourself to these patterns, the more confident you’ll feel on test day.
Happy prepping!
