Thank you all for your replies. My son is a Junior and will be applying for schools next year. I think he is worried that by the time he applies, colleges won’t take it into account that he was part of the first batch with new Essay format and scoring guidelines. He was expecting the score to be 34 as per old scoring style with 11/12 on all categories. but from the post from @fireandrain, it looks like his conversion to 31 is inline with what others have experienced. Anyway, I think as @Erin’s Dad said, it is not worth a retake, instead he can do something else this year to build up his profile for colleges he will be applying to.
