Easiest VISA route

I know this is a long shot, but I really want to move to London early next year. I already have a masters degree (speech therapy), but the HCPC process is so long that I’m not sure I will be able to move by then. I think getting a student visa would be my best shot at moving there, however, I obviously don’t want to pay much for it. Does anyone know of ANY degree that would be cheaper? Maybe an in-demand degree that the government is looking for more workforce? I’m willing to study just about anything. TIA!
