Student Physio was set up by Physiotherapists working in elite Football, Boxing and strength-sports.  Our intention is to provide therapists with something we never had as students - concisely presented but highly detailed content following a structured syllabus.  Our goal is to ensure that anyone who completes our courses leaves them as an EXPERT in that particular area.
Also, something that I've found is that if you go wrong somewhere instead of mindlessly searching for the error (assuming there are multiple or you don't know the error's location) just start from the beginning and go down seeing that if this works. If you see a break and something disconnects, in all probability that's where the error is. It's all logic.
I can’t recommend Harvard’s CS50x Introduction to Computer Science enough. You can audit the course for free via edX and earn a certificate by completing all the assignments, or you can go at your own pace and watch all the lectures posted on Youtube. You can build your own DIY college-level computer science program with this selection of fifteen online courses (many of which are also listed in our Lifehacker U series).
Code Avengers are based in New Zealand. They also offer Code Camps where there’s 1 to 3 days of coding training. These camps are located all over the world and in various states in the US.  You can learn coding languages such as C++, HTML, Python, game design and many many more. They also offer these courses in multiple languages, making it accessible to all.
EdX is another leading online-learning platform that is open source instead of for-profit. It was founded by Harvard University and MIT in 2012, so you know that you’ll learn about cutting-edge technologies and theories. Today, edX includes 53 schools. You probably can’t go wrong with the free Introduction to Computer Science from Harvard University.
