We propose three strategies to improve the accuracy of the calculation of the hadronic matrix elements relevant to the semileptonic K-, D, B-decays. Illustration is provided for the D-decays form factors F+(q2) and F0(q2), extracted from the correlation functions computed with twisted boundary conditions on the configurations produced with Nf=2 O(a)-improved Wilson quark.
