Letters / This person's three characteristics in greatest need of development? Statement? [3]

Many thanks Hannah Grierson. My job done :)

Scholarship / 'whatever the setbacks are..' - short scholarship [4]

I catch your meaning and what you want to say. However, I think you have to make various kinds of sentence such as simple, complex...to make your essay more colorful. One more thing I want to share with you is that the basic high school essay should be organized in the following five paragraph structure:

Introduction
Body Paragraph One
Body Paragraph Two
Body Paragraph Three
Conclusion

Good luck with your scholarship!
