If stall is 40k, I would expect touchdown to be at about 41.
Not unless you are very lucky or VERY good, most people will probably touch down 5 kts or so above the stall, the whole thing of actually "Stalling it on" is very misleading, even in a taildragger.
Randomtox -
What has been said up to now (relax, small corrections, try NOT to land) are all good, but I would point out that at the momment your instructor is probably only trying to give you as much handling as possible and will actually move on to TEACHING you how to land in the next few lessons - give him the chance
