Hi everyone, I just got back my TOEFL scores and i got 106. I got r=28, l=28, s=29 but writting only 21, and i dont agree at all. I dont really need any specific mark any more (106 is enough) but im thinking on asking the rescore of the writting section... What do you guys think? Do they change marks or is somethign really weird? Thanks!!!!:)
