This summer vocation, the summer vocation before my junior year, has been filled with many kinds of preparation classes, such as SAT prep class and TOEFL prep c;ass. I had SAT prep class for the first month of my summer and TOEFL prep class for my second month of summer. The SAT prep class is pretty helpful, and I improved my writing skills. Although my math score dropped, I got a higher score on total score. In the SAT model test I took during sophomore  year, i scored 710 on math, but now i score lower than that.  Writing score and math score is easier to improve comparing to reading, and you gain less improvement on reading score with same amount of effort. I'll try to focus on math and writing because my total grade will improve more.
