I have a question about Elite SAT Prep Cles?

Please share your thoughts if you have attended Elite's prep cles. I'm a sopre, and I took the psat around fall, when school started. I did horrible, and I got 150. I thought maybe I lacked some of the information because I was just beginning my sopre. Anyways, this summer I am motivated and determined to study for the SAT and I'm wondering is Elite will help me? If i decide to join, should i start by just taking the regular cles, or go straight to the boot camp? I am willing to put my time into the work they give me, and I seriously want to do well on the SAT by getting 1900+ .
