It's pretty basic HP fanfic with an OC MC.
It has two plot-lines going on.
One MC learning magic, and while his starting point isn't great, it doesn't take long for him to start getting OP. Though there isn't any secret to it really other than him putting in most of his time and effort that a lazy child wouldn't. And room of requirement.
(overall this plot-line is very basic but well executed)
The other is MC dealing with the problems that come from the canon storyline. And well... things go very smoothly for him all the time. I will give it some props for MC dealing with stuff himself, rather than baby sitting Harry Potter like most fanfics do, but nonetheless, the ease at which MC deals with each problem without any problems arising make it boring.
So ultimately, I would settle for this being rather average HP Fanfic, though someone that didn't read many HP fanfics could probably appreciate it more than me who read through this formula several times and seen better.
