Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.

You are going to have a tad of the thinking yourself. I will be happy to critique your work. Of course, you have to know 30 percent by mass of WHAT.
