如果你申请了LEED AP的资质，就必须一次参加4个小时的考试；如果你没信心一次通过全部考试，可以先申请LEED GA的资质，只考Core部分，通过以后，凭GA的成绩再去申请AP的考试，只需要考Specialty部分。 

原文如下：
Unfortunately, splitting your current exam is not possible. However, I can put the exam application on hold. It will retain the same expiration date. You can then apply for the LEED Green Associate, pay the application fee and take the exam. Once you have successfully completed the LEED Green Associate exam you can contact us to have your LEED AP application taken off the hold. If this is the method you would like to take, please create a new email acknowledging you understand the above process and we will be happy to assist you.
