I have an attribute 'Exam' that can have only two values 'Even ' and 'Odd'.
So how do I set it in the table? like a bit value ? or like varchar?

What I have tried:

if I use varchar, then the column has only 'Even' and 'Odd' values. so that will lead to normalization issues?

If you are absolutely sure that you will ever have only two values for this then go with bit. Consider 0 as even and 1 as odd.
