Here is the link to the playlist of videos that explain all of the math questions in the 2023 May SAT QAS that was held in the US on the 6th of May.
SAT math practice question: Exponent equations
Try the following SAT math practice question (Calculator Permitted) that tests your understanding of algebraically manipulating exponent expressions.
Question(Calculator Permitted):
$$ (\sqrt{27})^{m} = \sqrt[3]{(81)^{n}} $$
If $m$ and $n$ are positive numbers in the equation above, what is the value of $\displaystyle \frac{m}{n}$ ?
- $\quad \displaystyle \frac{3}{4}$
- $\quad \displaystyle \frac{8}{9}$
- $\quad \displaystyle \frac{9}{8}$
- $\quad \displaystyle \frac{4}{3}$
SAT math practice question: Exponential functions
Try the following SAT math practice question (Calculator Permitted) that tests your understanding of percent changes in exponential functions.
Question(Calculator Permitted):
The exponential function $h$ decreases by $36\%$ for each increase by $2$ in the value of $x$. Which of the following could define $h$ ?
- $\quad h(x)=3(0.36)^x$
- $\quad h(x)=2(0.64)^x$
- $\quad h(x)=3(0.8)^x$
- $\quad h(x)=2(1.36)^x$
The Official Digital SAT Study Guide release date
The Official Digital SAT Study Guide will be released on 1st August 2023 by Collegeboard. The guide will have four practice tests and sample questions. Currently, we don’t know if these tests will be identical to the ones in the Bluebook app or the linear practice tests (non-adaptive) that have already been released by Collegeboard.
Skills Insight SAT: Video explanations posted
The SAT Skills Insight tool helps students interpret their digital SAT scores, and also allows them to see sample questions from different domains and difficulty levels. Collegeboard has released a set of 56 Digital SAT math questions that are organized by difficulty and belong to the following four domains: Algebra, Advanced Math, Problem Solving and Data Analysis, and Geometry and Trigonometry. These set of questions can be obtained from Skills Insight SAT Tool link at Collegeboard’s Digital SAT website. Here is the link to the playlist of videos that explain all of the math questions that are part of the Skills Insight SAT tool.
