Let $x$ be the number of students in the math club.
Then the number of students in the science club is $2x$.
We know that there are $3$ students in the math club and $3$ students who are members of both clubs. Therefore, there are $3-3=0$ students who are only in the math club.
We also know that the total number of students who are in the math club or the science club (or both) is equal to the total number of students in the math club plus the total number of students in the science club, minus the number of students who are members of both clubs, which gives us:
$x + 2x - 3 = 3x - 3$.
So, the total number of students who are in the math club or the science club (or both) is $3x-3$.
Since the total number of students in the math club is $3$, we have $3x=3$ and $x=1$.
Therefore, the total number of students who are in the math club or the science club (or both) is $3(1)-3=\boxed{0}$.
Annville Junior High School has a math club and a science club. There are $3$ students in the math club and $3$ students who are members of both clubs. There are twice as many students in the science club as in the math club. Find the total number of students who are in the math club or the science club (or both).
