Hello all! 

I retook the GRE yesterday and was very satisfied with my new scores. However, while writing both essays I cut it really close on time. This resulted in fully developed body paragraphs, but somewhat stunted intro/conclusion paragraphs (particularly conclusions). The ideas were clear, cogent and summarized well (I like to think at least), but they were only a few sentences because I literally ran out of time. 

How much do you think this could damage my scores? These were much better essays than my first GRE, from what I remember, and I scored a 4.5 I was aiming for a 5 or above, but I'm worried this lack of development could really damage it.

Thanks!
