@CuriousOne If he has trouble with math, he should work on improving his skills: learn the necessary tools and improve his mathematical thinking along the way. Given enough time and effort, he can still become good, even at theoretical physics.

comment Direction about future
@CuriousOne As an example of what one has to expect at the university level, your suggestion is definitely a good one. Establishing a correlation between mastering Landau/Lifshitz at high school level and becoming a successful theoretical physicist is, however, a little bit far-fetched, as there are many factors that come into play. But you are right that reality is though, and that you have to become really good at what you are interested in.

comment Direction about future
@CuriousOne Starting with Landau/Lifshitz at high school level seems to me like a bad idea in order to gauge one's interests and capabilities. As it is not intended to be read at that level, it will be unnessecarily discouraging to most people. As the poster is apparently not satisfied with his own mathematical abilities, it would be a much better start to make up for deficiencies in that area and then make the transition to physics problems at undergraduate level.

comment What symmetry gives you charge conservation?
You write that it is gauge invariant off-shell if we demand $\partial\cdot J=0$. We do not have to impose it, this is always true for a conserved quantity.

comment What symmetry gives you charge conservation?
But that is not true. You state that it is gauge invariant if $\partial_\mu J^\mu=0$. According to Noether's theorem, this holds for a conserved quantity, even off-shell.

comment Why does the QCD vacuum have zero momentum?
@AccidentalFourierTransform This is actually the case in the vacuum of QCD without quarks, where there is a periodic degeneracy of vacua, described in terms of the $\theta$-angle.
