Revision questions for final exam DC circuits

Here following are some study questions.  The first large circuit has a video solution here also “I like coloured pencils”

You need to find all the resistor voltages and currents.  You should also think how to construct this on a breadboard.  Draw it up on a breadboard layout and think through your process.  The use of colours helps with these types of circuits.  Don’t forget to see the accompanying video solution part 1.
