God Bless for the “Accredited Symbian Developer” Exam!
ASD考试好难，绝对不是一个让你feel good的考试！IKM exam考试网页上的官方说明：
This assessment contains proprietary testing algorithms which will adjust the degree of difficulty of the questions to match your particular level of demonstrated expertise in the subject matter being tested. The questions will become increasingly difficult if you are doing well, or will become increasingly less difficult if you are doing poorly. As a result, no matter how proficient you are, the test will seem quite challenging, and you should not expect to answer every question correctly.
When the test has been completed and your answers have been returned electronically, a comprehensive profile of your expertise in the subject matter being tested, including your knowledge and practical experience in the subject, will be generated. Your skills will also be benchmarked against the universe of test takers in this subject.
因为之前也看过一些关于ASD的评价，由于采取的是自适应的算法，他会根据你的答题总是出比你能力水平稍微高一点点的题目，所以考试过程中碰到难题到是挺开心的，说明前面的做的不错，我觉得这种心态很重要，不然很容易就放弃了，因为有些题目难得基本就看不懂，没法做。
如果难度是从0–100的话，因为仔仔细细研究过他的sample questions（表明了难度等级），我的感觉刚开始可能在70左右，前面几道虽然有点猜，但是估计做的不错，一下就很难–难到看不懂那种。后面开始回落，并一直保持在70左右，中间偶尔出现几道比较容易的题目，然后又上去了，出现了几个难得看不懂的，然后又下来了，但是最后两道题目我感觉特别容易，不知道是什么意思。考试的estimated time是57分钟，我大概花了72分钟。中间还断了一次线，把浏览器关掉后重新开一下还是可以继续的。另外说一下，考试时间还是很pressing的，就算旁边有本书基本上也没有时间去翻去找。
在开始考试之前，会出现一系列的提示，看了一下，大体如下，有些和网上说的不太一样：
1，每个问题最多有三个答案是正确的，对的选中得分，对的未选中扣分，错的选中扣分，每个答案都有各自的权重。
2，关于猜答案：基于1，如果能将可能性缩小到2个可能对的，那么选他们；如果你实在猜不到，那么最好还是跳过这个问题（我看那本书里面说选一个你认为最接近的正确答案），因为错的答案比跳过问题更不好。不知道该相信哪个，呵呵。
3，速度和准确率：速度会作为一个因素，但是准确率更加重要，虽然这么说，120分钟肯定还是够用的。
Review：
1. Each question may have up to three correct answers.
2. You may select up to three answers for each question.
3. Skip a question if you have no idea of the correct answer.
4. If you are able to narrow down the answers to two reasonable choices, you will always get some credit if you select them both and at least one is correct.
5. You may not go back to a question once it is answered or skipped.
6. Answering correctly is much more important than answering quickly.
7. For each individual question, time will not be tracked until the question is presented in your web browser.
8. Once the test begins, you must directly proceed through the test until completion.
