The questions are not too complicated. If you have a good approach and spend time on a couple of questions you will see they become very repetitive
Addition polymers example:

1. Move all bonds not involved in double bond to the vertical position
2. Redraw the structure 3 times without double bond
3. Connect those 3 repeats together
Condensation polymers example:

This is the other way around but if you want to go from the two reactants to polymer
1. Remove 1 water from inside of the monomers and 1 water from outside of the monomers
2. Join together and put bracket and n
