Info about how I have done this is in this thread. I haven't needed to alter the database structure.

Be very careful with alternative mark schemes. The scheme you propose here (1,2,3 if correct or -1,-2,-3 if incorrect) is unsatisfactory because it does not motivate a student ever to use options 1 or 2 to identify that he/she is uncertain about an answer. With this scheme it is always best either to opt for high confidence (3) or to refrain from answering at all (yielding zero). Students will either understand this, or else lose out by using options 1,2 to their disadvantage. This is discussed and explained further in publications on the LAPT website, for example in GM & Gahan (2003) (referring to scheme B in Fig.4).
