Which test to use except x2 for nominal variables

[Curtains White]

Dear TalkStatsers,

I've been puzzling my head all weekend as to what statistical test I should use for the following question;
"Who do you think is better in Mathematics?"
A. Male students
B. Female students
C. There is no differentiation according to gender

I started by using a x2 independence test because I have two nominal variables. However in a note under "Chi-Squate test" table, said that more than 20% of my cells had expected count less than 5. So, my results from this test are not valid and I have to use another test.
My problem is that I don't know which test to use. If someone knows, could you please give me some advice?

Thank you in advance for taking the trouble to help me!!

You could try a permutation chi squared test.

Hi,
actually you have only one variable : gender and this has two levels Male and Female. Maybe you did not set up the Chi-squared test correctly?
