### 5/5 — Great learning tool!

*2015-07-09, version 1.0.2*

Simple design, easy to use and educational. Very good app for those trying to wrap their head around electrical...not literally....you get what I mean!

### 5/5 — Very Good App!

*2013-07-08*

Nice tutorials and quizzes on a variety of electricity topics.

### 3/5 — Ben

*2013-06-08, version 1.0.2*

Good app, except the key skills quizzes do not correctly score your answers but rather, changes the answer you selected once you finish, seems like a small bug that requires fixing.

### 2/5 — Question wrong

*2013-02-19, version 1.0.2*

QUESTION 5 on GENERATORS IS WRONG.
A commutator is a vital part of which type of generator?
It says the answer is d.c when it is actually a.c my physic teacher told me so, and so did Wikipedia.

### 1/5 — Mr

*2013-02-01, version 1.0.2*

I think the person who comes up with the questions needs to go back to school himself. It is the ignition coil that produces high voltage to produce a spark for the spark plugs not the alternator, that is to charge the battery.

### 5/5 — Awesome app!! Would have paid for it!!!
