見せてもらっておきませんか？？
 

I wanted to ask my Japanese Teacher if she would check something I wrote for when ready for when we have class next time. But I think I was mistaken..
Is said これを見せてもらっておきませんか。 Wouldn't this normally mean would you let me take a look at it? How would I ask properly? Simply　見てもらってもよろしいでしょうか e.t.c. I think i'm abit confused with what someone taught me before.

Thanks,
Jamie

I agree with masaegu, basically.

Only this time:
見せてもらってもよろしいでしょうか。
これを見せてもらえますか。
