  We have obtained the differential decay rate and calculated the branching
ratios of the exclusive semileptonic decays $B(D) \to Xl\nu$, where $X$ is a
p-wave meson, using the nonrelativistic ISGW quark model. Our results are
compared with the predictions of the ISGW2 model. We have computed some
branching ratios that were not reported or were reported with 0.00 in this
model. For example, we find that $Br(B_c^- \to \bar{B_{s2}^{*0}}l^-\bar{\nu}) =
4.03 \times 10^{-5}$, $Br(B_c^- \to \bar{B_2^{*0}}l^- \bar{\nu}) =3.65 \times
10^{-6}$ and $Br(D_s^+ \to f_2l^+\nu) = 2.7 \times 10^{-5}$, which seems to be
at the reach of forthcoming experiments. Furthermore, we have classified the
$B_{u,d,s} \to Tl\nu$ decays in two groups and compared the semileptonic and
nonleptonic decays including a tensor meson in the final state.
