Do people find solving PDEs involving characteristics, expansion waves and shocks difficult? I find it extremely difficult. It is hard to get one's head around it. Are there any ways of making it easier?

To the shock problems, according to my experience, discrete singular convolution (DSC) method would be a feasible and even better choice for such kind of problems!
