Perfect. Universities have been postponing classes here because of nationwide protests so I've been using this course to catch up on Java I'm supposed to be taking, and it has been a seamless experience so far. Teacher is clear and concise and has a nice way of explaining things. Didn't expect this high of a quality from a free course. Thank you!

  After working as a software developer and contractor for over 14 years for a whole bunch of companies including CSC, Proquest, SPSS and AT&T in the UK and Netherlands, I decided to work full-time as a private software trainer. After spending four years in the beautiful city of Budapest, Hungary and a year in Berlin, I now live in my home town of Derby, UK.
