Point to a two-dimension array

There is a two-dimensional array:

int grades[MAX][MAX];
for( i = 0; i < MAX; i++)
   for( j = 0; j < MAX; j++)
      grades[i][j] = -1;

I would like to assign an another variable to this array, for example:

int another_grades[MAX][MAX];
for( i = 0; i < MAX; i++)
   for( j = 0; j < MAX; j++)
      another_grades[i][j] = grades[i][j];

Here, I need to declare another array.  Is it possible to have a
pointer to point grades[MAX][MAX]?  As I've tried:

int** another_g = grades;

it does not work.  Any good idea?
