Basic Electric Circuits Kit

Its been a while since I've needed to do any maths or physics. Working through the book is going quite well. I did have to look up on the Internet how to actually do the maths again, but once I worked out where I was going wrong I was set. Perhaps a little step by step to show the working for the first fraction calculation initially would be a good inclusion. The kit was missing jumper wires . . . while this was annoying for me I have a lot lying about. For someone starting out this is an instant show stopper. A little more QA may be required. Book 4 stars, missing jumper wires 2 stars.
