Just how hard is SAT math if it doesn’t test really high level math topics? It doesn’t even get to trigonometry. Yet, at the same time, it’s meant to challenge even the most advanced math students. There’s a pretty clear problem there. How do you sort the best junior or senior year math students from the 9th graders who are constantly sneaking in to take the SAT? (Alright, so that doesn’t really happen).
In order to assess students well, the test-makers resort to other ways of making SAT math difficult.
Complicated question setups
Even the most astute students find that sometimes the hardest part is just digging through all the information in a convoluted word problem. Instead of simply giving you an equation or providing a figure, the whole thing will be written out in sentences, and it’s up to you to set up the math or draw the situation. That can be seriously difficult, depending on how complicated the equation or picture is.
Topics you learned three years ago
Learning math is a cumulative process, for the most part; what you studied in 8th grade gets used in your 11th grade math class. But that’s not always true, and if it’s been three years since you’ve even looked at shapes, you might be a little hazy on your SAT-type geometry.
But this situation is pretty easy to get around, thankfully. All you have to do is review.
Okay, so you know how to deal with average rates. Can you work with them if there are two variables in the picture? Or maybe you’ll get a geometry problem that includes a few different types of shapes. Or maybe the SAT graph you’re facing is spiced up with a little geometry to boot.
Difficult SAT math questions might have a number of steps. Getting to one correct answer in a more difficult problem might involve three or four times as much scratch work as finishing a question at the beginning of a section.
The key to problems like this is to take them one step at a time. Don’t take shortcuts unless you’re 100% sure that you’re not going to slip up. Write everything out, and always put parentheses around any terms that you plug in so you don’t make the classic positive/negative mistake. The good news is that there are also ways to improve SAT math. 🙂
