If you have already attended one of our courses this part of the site is just for you. Welcome back!

All you have to do is to login using the code that was supplied in your course manual.

In these pages you will find lots of additional information that we just didn’t have time for as well as some calculation exercises that will help deepen your understanding of some of the concepts that you encountered during the course.

You can visit this part of the site as often as you like and stay for as long as you like. We hope you find it useful and stimulating. If you don’t find what you’re looking for or there is some information that you would like to have included, please let us know and we’ll do our best to put it in.
