1) About the cover letter, we are required to
"Describe your accomplishments and include an example of how you had an impact on a group or organization".
The issue I see is that I may overlap my accomplishments written in the CL with the essays' stories. For example, one of my accomplishments fits perfectly well in the essay question 3. And it is likely that in the 2nd question I will use another of my accomplishments described in the CL.
Should I use different strategy? or it is fine to repeat things? Could I write something like "please see question 3 for more detail"?
2) I have a big story for question 1, but the problem is that it occurred 5 years ago. However, it had great impact in myself, personally and professionally. In fact, my career has been influenced for that decision and I think it is essential to write about it as it shows them a lot about who am I.
Do you think it will be a big issue to write about something that happened out of the 3-years period? I could use the additional essay to explain why I decided to write about it.
3) I have a third recommender that I'd like to add in the application. Do you think the fact of using an extra recommender may hurt me or otherwise help me?
4) About the 50 lines of the CV, it does include the "empty lines" or only the written ones? Do you think it is fine to go over the limit a bit? I have 54 written lines of the CV submitted for other schools...
