SAT writing is really testing understanding of vocabulary, grammar, colloquial English, style, argument flow, and common usage. These can all be learned quite easily. Most students have weaknesses in just a few areas. By identifying and concentrating on those areas, rapid improvements can be made. I can also help with writing an essay that will impress colleges, beyond your grade level and overall SAT score. My most recent student scored perfectly on this section. I've helped students improve by as much as the equivalent of 90 points on this part of the new SAT.
