Simple scoring system help?

Thanks for the video! It’s exactly what I want for another part of the project so I’ll definitely be bookmarking it, but It doesn’t help with this question.

I’m new to UE4 (Obviously, haha) I generally focus on the modelling and animating side, so I have absolutely no idea how I’d go about implementing a score system at all in UE4 never-mind making it go up by 50 points every second.
