Which General Physics Topics Are Considered Easier to Understand?

[AzzidReign]

I was thinking of putting this in the General Physics forum but there it stated that I'm not allowed to post anything dealing with school, but on this forum it states that I'm only allowed to post problems, but my question doesn't deal with a problem, it deals with topics in general.
If this needs to be moved to the General Physics forum please do so.

Question
These topics have been covered so far my class:

-Potential differences and changes in energy
-Capacitors or resistors in series/parallel combination configurations;along with energy stored or power
-RC-Circuits
-Mass spectrometer
-Force/Magnetic field due to current carrying wires
-Changes in Magnetic Flux and the induced emf/current
-Refraction/dispersion
-Lenses and mirrors with ray diagrams

Out of those, which ones are a bit easier and less time consuming?

For whom? Why would someone else's subjective answer to than be helpful to you? Seems to me it would be more helpful to you to figure out which ones YOU think are easier since that might point you towards what kind of studies YOU like. Why care what others like?

Well I asked to find out what other's would think so that based on their response I would find ways, other than the ones I already know now, to solve problems in those topics.
