Google Training

The information here, on the top few links, is from the Google Apps for Education Training Centre.

If you want to become a certified trainer, you can sign up, pay the fee for each module, and complete the tests. They are all open book so you don't have to memorise anything.

The information is there to read and learn even if you don't want to pay and sign up.

The rest of the links are Google courses that are free to do.
