What fields would an undergrad in physics be introduced to?

[QM_0]

Just trying to learn modern physics.
Currently studying (Classical Mechanics, John. R. Taylor).

What else should I try studying?

My goal is specialize in either Particle physics, Cosmology or Quantum Mechanics and Quantum Computation.

I'm a senior undergrad. When I finish, I will have been exposed to E&M, QM, Classical, Circuit Analysis, Stat Mech, a survey of modern physics, and a year of upper division lab. I think every undergrad is required to have E&M, QM, Classical Mechanics, and Stat Mech. Some of the more rigorous schools have serious introductory classes on atomic and nuclear physics, particle physics, and relativity for undergraduates.
