Summary for software designer exam for May 23rd 2015

I spent about 2 months to prepare for this software exam. Because I am majoring in computer science and technology, I have already learned about some tasks such as Operating System and The Principles of Compiler, etc. I have some basic knowledge and it's more easy for me to prepare for this test.
I searched for quite a lot of materials such as real test papers, review summaries and so on. I firstly went throught all materials by modifying and adding new knowledge to the existing documents. So these docs contain my thought and it really helps me to have an overall view about the knowledge about computer. But I also know, it's just temperate because after the test I will forget about these knowledge. The best way to absorb knowledge is to use it.
A few days before, I found I passed the exam with 68,65 scores. It's enough for me to pass it but I know I am lucky because I tried my best to finish all questions and don't give up. So I think it's my secret to success.
