Hi, I received my paperback, and I received a B+, I asked for an appeal to re-grade that paper, and they asked me to present a justification and explanation of why I need this paper to be graded again. Can you ask the writer to go over it and give me some reasons based on my advisor comments
this is also one of his comments and the rest is in the paper i uploaded:
This is a solid piece. South Korea is an important country and its relationship with the UAE is significant. Moreover, the country is a model for many developing countries. Regarding the domestic factors impacting South Korea’s foreign policy, you did an excellent job in making the case. However, in some of the cases you were trying to demonstrate the argument by linking external factors to foreign policy. In other cases, you claim the impact of domestic but you do not back up your claims with evidence or empirical examples.
The citations in the paper need revisions and the paper exceeded the number allowed 2000-2500 (you have 3239 words). Nonetheless, I believe it is a good paper. Keep it up.
