- Optionally, it would be a good idea
for you keep some kind of notebook
as you worked through this course,
particularly as there are a few places
where I encourage you to do some small exercises
that will help your understanding.
Something like this will be perfect.
You can draw,
make your own notes, and stick reference items into it.
The handy guide that you create will be your own reference
that you can use when ever the need may arise.
So if you can,
I highly encourage and recommend you to do so.
