GARP发过来的考试注意事项中有如下这条，是指什么意思啊?错了要改也要保留错的答案，再选最终答案？如果改过几次怎么办？哪位能解答一下吗？


   
How  do I change an answer on the Answer Sheet?
  
   
If you want to change  your answer to a question on the Exam, you must complete the Final Answer  column. For example, if you fill in bubble A for an answer, and then decide  that you want to change that answer to C, DO NOT ERASE your initial answer  (A). Leave bubble A filled in and then ALSO fill in the bubble for C. Then  you will ALSO need to write the letter C in the column marked Final Answer on  the Answer Sheet.
  
  Do not write in a letter for every question in the Final Answer column, just  the one you are changing. Please observe the poster of how to correctly  change your answer that is displayed in the Exam room. Answer Sheets that are  not completed correctly may cause a delay in your results.
