Let \( n \) be the total number of students in Ms. Quarles' classes. According to the problem, she grades 25% of the tests, which equals 30 papers. We can represent this mathematically as follows:
\[
0.25n = 30
\]
To find \( n \), we can solve for \( n \) by dividing both sides by 0.25:
\[
n = \frac{30}{0.25}
\]
Calculating the right side:
\[
n = 30 \div 0.25 = 30 \times 4 = 120
\]
Thus, the total number of students Ms. Quarles has is
\[
\boxed{120}
\]
\[
0.25n = 30
\]
