The OU Job Board Training used to offer courses, but I’m not sure if they’re still available.
If you’re a resident of New York City, you can qualify for a free Lynda.com subscription by getting a New York Public Library card – the website has many high-quality tutorials in many different technical topics. You can pay for a subscription also but it’s expensive. Pluralsight can also work.
There are also many free tutorials, but usually paid ones are better.
