>im Student!!
That's obvious from the conventions used in your code.

>there might be some mistakes...
There are a lot, actually. I don't have the time to point them all out right now, but I will when I can. That way everyone can learn, including you.

>so i thought that perhaps it could be helpful
I applaud you for it, but keep in mind that bad code is less helpful than no code. It teaches others bad habits and poor practices. Since you're a student and you clearly recognize that you're not an expert, maybe it would be better to ask for advice on how to improve your code rather than just posting it with the implication that others can learn from it.
