I have recently started an online Course with Wolsey Hall Oxford that I fully recommend to all Home Edders out there.
You can choose from lots of different subjects including Maths, English, French and many others.
I have started Maths and more than likely will start computing as well fairly soon.
You have the course sent to you, but you have an online tutor who you can contact if you can’t do something and they will send you a video telling/showing you how to do it.. You work through modules (for instance Temperature) and when you have finished all the required modules you can do a quiz, which if you get more than fifty percent you will unlock the assignment for that module. You print that off complete it and then send it back to your tutor who will mark it. Once completed you will move on to the next module.
It’s challenging, but I’m enjoying the one I’m doing.
