When you really don’t feel like learning and you just cannot concentrate, how do you get things done? How do you focus on the topic if it’s boring but necessary?

When I don’t feel like getting anything done, I do the hardest task first and then do the easiest last. This is kind of like a reward. I focus by telling myself I can do it and I get it done so I can do the other things I love. I would suggest making your environment calming to help you.
