Take your time 
I gave up on doing things for now. Got to the point where I can’t do in half day effort anything better then I have done before, and I don’t want to spent more on models I don’t really need.
I don’t even follow with the models that are going in courses (I haven’t done pyramid, bowling scene, my chess set is way more different and I done it right after S03 and before actually doing S04 as I figured at once that they have little to do with what going in lessons) I did lamp nicely and added a correct rig to it, but decided not to animate it, animation is a serious topic that I will need to study much more extensively after this course anyway. I’m not even following with that bunny. I just use basic shapes and models to try out stuff shown in lectures.
Something like this: “my version of that fluffy bunny” 
(don’t mind the face, it is that ancient crude greeny I done month ago)
Sculping human head I will do with maximum effort, will easily spend days on it because I will use it in my work later on, so there will be real serious work

.
And a 2hour effort at
plane
model for the other topic. Wanted it to be few minutes work but ended spending two hours at it
