Simplifying a circuit using Thevenin
These schematics are frequently drawn in a nonstandard or unusual way to get you to think about how things are connected.

One key to figuring them out is to redraw them so that you can more easily parse what things are in series and parallel.

Here is my suggested redraw of the schematic. It isn't as simple as it looks... hence why I had to edit this post a few times. I leave you to figure out the rest.
