appointment last approximately 4½ hours 这是啥意思啊。。。

During these dates, your test appointment will last approximately 4½ hours. At the end of your standard GMAT exam, you will be asked to answer 12-15 additional questions during a special 30-minute research session. These questions will not count toward your GMAT score and will not be shared with schools. You will receive a reward if you put forth reasonable effort to answer these questions这个回答问题又是什么意思呢？请多指教！

因为多了那半个小时的12-15到题的加试，你的考试时间总计会延长到4个半小时。加试的分数不算到GMAT的成绩里的。加试就是各种测试题。

我想如果是在做完了之后再来加试，那就好，千万不要像ETS一样在做的过程中搞点多的出来……我都不知道哪些是加试就悲剧了……

4个小时的考试本来就有加试题啊，这半个小时的加试会和4个小时的考试区分开来吗？还有，这半个小时加试的是verbal还是数学啊？
