I don´t know wich DAW you use, but no matter wich one it is I´d recomend watching a few tutorial videos on it. The BPM is the speed of your track. If your melo and drums are a different bpm, you can try stretching those to fit the same tempo as your beat (again, watch a few tutorials, they go in depth with that stuff).
A hook is the part of your track that changes the beat up a bit for some diversity. It´s a bit boring to listen to the same thing over and oer again so you can add a counter melody or switch up the drums etc.

So in short: watch some vids about beatmaking on YouTube, there are quite a few of em that go pretty good.

ou my god that goes hard! but then goes completely off sync :/ no hook either, I´m pretty sure your melo doesn´t fit the bpm of the drums. It started out hella sick, and then kinda went downhill from there.

In conclusion
B for effort, started strng, didn´t end nearly as strong.

Still, 7/10. If the melo and drums would be in sync: 10/10, sadly, not the case.
