Which prep books to use to get perfect scores in SAT subject tests?

For colleges I want to apply , I need 800 in maths 2, physics and chemistry. Please guide me.
I have ordered Barron and Princeton. Are these sufficient?

I don’t know about physics but for math and chem barron’s is good

Those books should be good, but don’t stress about getting exactly 800. A 750+ is more than sufficient.
