Most financial math books in the market are too theoretical rather than practical. My friend as one of the top quants in Sydney always tells me that the new comers in her company know theories quite well, but they don't know how to do modeling in practice. Therefore I would suggest that while you are studying financial math, a companion book about applied numerical methods should be used as well. This is particular useful when it comes to the simulation of option prices using monte carlo simulation, optimization for model calibration and solving SDE and PDE using numerical methods such as finite difference, finite elements and simply Euler's.
