Example answers and how they were marked
Full marks2/2
1111 1110
Why: Each digit is 4 bits: F = 1111, E = 1110 (2).
Some marks1/2
1111 1111
Why: Converts E as if it were the next digit up. The first nibble is correct (1); the second is not.
No marks0/2
1110 1111
Why: The nibbles are in the wrong order. Neither nibble is correct.
