We can rewrite the asked question like this:

wherein X_1 and X_2 are random variable with the same given normal distribution. Then mean of

is zero and the variance
can be computed like this:

So, the random variable

follows a normal distribution
with means 0 and standard deviation 9.6.
The median of the law N(0,9.6) is 0.
So the expected difference of the score is 0.
