Synopsis until the exam

After graduating from graduate school, I got a job at a major manufacturer and seemed to be able to lead a stable life, but I could not find any pleasure in my work and retired. When I started learning programming, which I had been interested in for some time, I forgot the time and was absorbed in it. Then he decided to change jobs to an engineer and started studying Java in earnest. I decided to take the Oracle Oracle Certified Java Programmer, Silver SE 11, which is evaluated to some extent in my career change activities.

Teaching materials used

A refreshing introduction to Java: Needless to say, an introductory book. First of all, I read this 3 laps. It's better to actually write the code, but I rarely write it. It was just a study method to read.
Purple book: Purchased the first silver exam preparation book. To be honest, it's hard to understand, but I'll do my best to read it for two weeks. I don't think I needed to look back now, but there are tables that can be used, and it was useful in some parts. If I couldn't understand the black book, I used the purple book.
Kuromoto: This is also a well-known masterpiece. I did 2 laps and went 3 laps only where I made a mistake on the 2nd lap. The image that the exam had about half of the questions with the same contents as this book. I don't think the passing score will be so difficult if you do this. The final total finishing problem should definitely be done. I didn't do the mock exam until just before, but I shouldn't have considered it as a finishing concept because there are a lot of things that I haven't written in each chapter so far. As with each chapter, this should be done three laps.

Study time

I haven't measured it accurately, but I've been learning Java for about 3 months. I didn't know about the qualifications, so I was just killing time, but during this period I was able to understand clearly for two weeks. After that, I started studying in earnest to acquire the qualification. Since I continued studying for about 2 hours a day for about 2 months, I learned about 60 hours.

Test results

Passed. The passing score was 64%, but passed with 78%. I don't think this is a good result.

Finally

After studying the basics and systematically understanding Java to some extent, it seems possible to pass in a shorter time if you just go through the black book. However, I think it depends on whether the purpose is to pass the exam or to be able to use Java. In my personal opinion, I think it's okay to aim for qualification once. Because I was learning for the purpose of acquiring qualifications from the middle, but after acquiring the qualifications, I personally wrote a little code, but I was able to output what I learned even relatively. First of all, it seems that there is no problem with the feeling of getting a qualification.
