Help with WR and CR for an international

<p>I am an 11th grade highschool student from Europe and just like many other students I am taking my SAT exams this year. On my first shot at the reasoning test I got a 2150. Although it is a pretty decent score, in order to get a decent scholarship (as I can't afford paying too much for college, but studying in America has been my dream for a few years and I do not want to give it up) I nede a 'lot' more than that. Shortly, let me describe my first experience: 780 in math (one stupid mistake, math is by far my best section), 670 in CR and 700 in WR. I was pretty upset with the writing section because my score was lowered because of my essay grade (I got only one of the multiple-choice questions wrong). As you may have noticed, my major problems are CR and the essay. Could you please recommend some ways to improve my scores in these 2 sections?</p>
