The reason many instructors teach the bank select bits is so the students 
learn as much as possible about how the chip works before heading off into 
the other (possibly easier) ways of doing things. If the goal is to only be 
able to program the chip, they would just start with a higher level language 
and skip a lot of this material.

It sounds like the OP's class is one in which knowledge of the operation of 
the microcontroller is at least one of the goals. If that is a good 
assumption then, no, it won't help him to start using BANSEL now.

Those who replied with explanations about RP0 and RP1 obviously learned it 
that way as some point. Maybe by desire; maybe by necessity.
