My day was  went  very full. Or My day went very well. How Today is my last day of vacation. I organized my things for work tomorrow.  My papers are tidy on my desk. My desk was is very tide tidy. and it was with my paper. It was hard, but I won finished.

Your desk can’t be with your paper. The desk is the bigger object. How you have the paper or papers on or near the desk is what determines the accuracy of the sentence.

And is it paper—singular or papers—plural?

When you complete a task or something you are doing you have finished (finish is present tense).

Won is the past tense of win.

When you use the word won, that is used when referring to a race or competition or a bet.

Example: 1) I won the race.  2) We played the game and I won the bet. 3) The horses competed against each other and my horse won.

I hope this helps.

Your word choice like "won" was okay but I don't know if that's what you wanted to say to be quirky. I also feel like when you said 'my desk was tide" you meant tidy - but I feel like you meant the opposite. Since you used past tense, I'm assuming your desk wasn't tidy but then like you said, you got it organized for work tomorrow. I hope this helps!

*I'm not entirely sure what you mean to say here, so I'm not sure how to correct it. But perhaps a better way of forming this sentence might be "My desk was very tidy and my paper was on it," or "My desk was very tidy, and as was my paper." 

I hope I've been of some help. Good luck with your studies!
