What do you want to learn about? Photography is a very, very broad church with lots of different areas of specialty. Different types of skill can be learned in different ways, and some can hardly be learned at all, or at least not in a formal or structured setting.
And why do you want some form of recognised qualification? If you want to work as an employed professional photographer in education, the police, or some other governmental-type, badly paid and unappreciated role, then a qualification may help or even be necessary, but this isn't something that most of us want to do. If you want to work for yourself, then no clients will care whether you have formal qualifications or not, you will only be judged on your work and your ability to market yourself.
And, even if you do want to go down that particular route, an HND is far more specific and relevant than a degree. When I did my degree, many years ago, photography was a science subject, taught by technicians who couldn't teach, it's now an arts subject taught by people who can teach but who know little or nothing about the technical aspects, and most of the degree courses are only part photography and part something else.
And there's some truth in the old saying that "those who can do and those that can't teach" Good photographers are not necessarily successful and successful photographers are not necessarily good, with many of the people running courses doing so because they can't hack it as photographers . . .
Take YouTube tutorials as an example, some are excellent but many (perhaps most) are terrible. As a generalisation, many of the good ones are badly presented because those who know their business often can't project themselves as the experts that they are, and many of the slick ones have little or no worthwhile content. Many are just deceptive, showing heavily-retouched example photos that owe nothing to the techniques demonstrated. These are often sponsored by manufacturers or sellers, but some are part of expensive courses too. It's a minefield out there!
You may do better just by joining a camera club - the majority of members may be very average, but you'll learn from the above-average ones. If you're interested in sports or other specialty photography then you can learn just by watching what other photographers do, there are many different ways of learning.
