Hi Maria,
I don’t know what kind of courses you are looking for but can certainly reccomend some free online ones depending on what you are looking to do.

and also

These provide some taster courses that you can see if you like something and then have the opportunity at studying it at a higher level if you do, you just have a foundation and build on that.
The main piece of advice I would give regarding any course is pick something you enjoy. Don’t do something cause you think it will be a good job at the end because job markets come and go and vary depending on supply of skills and demand of workplaces. It’s far better to choose something you’re really into and at the risk of sounding cliche’ follow your heart. It’s far easier to learn when you’re interested and you enjoy it, also it doesn’t really matter what you study specifically because there are loads of transferable skills you will learn along the way. The important thing is to pick something you can immerse yourself in and feel you are going with the grain not against it.
Hope this helps and good luck! 🙂
