What do you mean by ratings? Do they want your opinion on what you think of their APIthe different sections? Do they want your opinion on how strong you think you are on the different sections? I too would like to know. (If I remmber right u cleared the test a few days ago.)
Your responses on the pre-exam survey will, in no way, effect the questions you get on the exam. The survey is there to help the folks at Sun improve their certification procedures. The questions you get on the exam and pulled randomly from a "question bank."
