I'm afraid there really isn't another way around. This stuff is just very difficult. If you want to understand the standard model you need to understand Quantum Field Theory, and to understand Quantum Field Theory you need to understand Quantum Mechanics, and to understand that you need to understand classical hamiltonian and lagrangian mechanics, etc etc, and to understand all that you need lots of mathematical notions, so... There really isn't a fast way but to study the standard texts.
