C :

#include<stdio.h>
int main()
{
  int s;
  scanf("%d",&s);
  if(s>=86)
    printf("VERY GOOD");
  else
    if(s>=60)
      printf("GOOD");
    else
    	printf("BAD");
    return 0;
}

Pascal :

program p140120;
var
  a:integer;
begin
  readln(a);
  if a>=86 then write('VERY GOOD');
  if (a>=60) and (a<86) then write('GOOD');
  if a<60 then write('BAD');
end.
