Anyone think it would be useful looking into magnetic moment?
Probably yes.

I know that the rules mention RC time constant questions, as well as capacitor questions, being permitted in division c. Would questions regarding other aspects beyond simple calculations of an RC time constant be permitted? I would think that if resistors and capacitors are permitted, then by extension, things like low-pass and high-pass filters would be allowed.

I would say yes; generally if you think it would be allowed, some test writers will too.

So just for anyone who might want to know what to expect on some tests here is list of things that you may see. I live in Ohio where the compititon is very hard, especially at State (considering that the national champs and runner up were from ohio). Anyways...here is the list:
- i always had a lab portion so become very good at identifying resistors in case they give you a huge pile
- a list of special symbols (sybols such as the ground symbol, switches, ect) put in your binder, just in case
- a list of inventors and when they invented things
- terms in SI units
that covers a huge part and might as well keep them in your binder just in case.............
hope this helps and good luck :)

Speaking of Ohio, the circuit lab test for div B had 5 different labs, 3 of which were done alongside the test and 2 of which were timed with each pair having 5 minutes total to complete both simultaneously. The test was also very very long, and very difficult. We only got about 3/4 to 4/5 of the way through and we still won.

So does this mean that there is the same info we need to know for the 2019-20 season?

There will likely be some small changes. We won't know exact details until the rules come out in September.

If you are interested in studying early for 2019-2020, I would encourage you to focus on the essential parts of the event, such as electromagnetism and circuit analysis. There is plenty of material here to last you til the rules come out in September.
To clarify, circuit analysis (for C division) should include Thevenin/Norton equivalents with and without dependent sources. Practice using the nodal and mesh methods, as well as understanding how to apply a supernode when circuits get complicated. Its also safe to say you can probably continue studying Op-Amps, since that is a big part of electrical circuits as well.
