The Center of Excellent courses are great. The course material is well delivered and is presented in a way that modules can be studied either a module a day or whenever you have the time. There is a chance to test your knowledge and think about your subject before submitting your assessment. I have purchased some of the printed material so that I can take it away with me and study when I have not got access to the internet. I can then make notes and complete a course locally and then up load the my answers when I do have internet. I have recommended courses to friends. I like to study the modules at this time of year (Autumn/Winter) as it fills the dark wet days! Thank you for the opportunity to learn and re-visit topics that we may or may not have covered during our school years.
