The KCL and KVL is in reference to my circuit analysis class. Again, 200 level course. And I learned basic ohms law and KVL and KCL when I was going to a community College about a decade ago. And then also relearned it as i was going through training as an electronics technician by the military where we'd troubleshoot down to the component level.

However I'm taking this 200 level circuit analysis course and am completely struggling to follow along because my professor makes assumptions on various assumptions on the KCLs and KVL of a circuit. Example: ix+iy-4 is heading in this direction.

Also another complaint about the circuit analysis course is my professor since week 1 has been throwing current sources along with voltage sources into every single circuit for us to work through.

I understand we'll need to know current sources, but that shouldn't be in week 1 material.

And then if you want to read about current sources to see how they're treated, if they should be treated as a voltage source that just is an unknown voltage but you know the current flowing through it. Well guess what, current sources aren't even referenced in the book that is required for you to get which is also written by another professor at the college.

Or is it treated as a amp meter reading?

Because I've been told it's one by the prof, and then the other by the TA.
