Sad to hear your result..
I think most of us (ok many of us) had a tough time understanding the derivatives PM session this time. I too got a score of less than 50. I also found there are not many practise questions available as your rightly said for derivatives.
I used Finquiz, even it didnt have too many Itemset questions for derivatives. But i found them very very good for the rest. Analystnotes is another one which you can try and you get to read the material free anyway as well.
I never liked schweser style and never used them.. May be you could give the above two sources a try.. If you search a bit on the net, there are many many sites which offer free questions, Just dont miss them. I had many many such sites, let me see if I can get the URLs from my desktop sometime this week and share it. Meanwhile these two sites below are you must be aware, just in case you didnt
