Do you want to research programming? I got six!

Do you want to study programming ？ Talk about my experience and views

Hello everyone , I'm fish skin , There is a problem that my friends have been very concerned about ： Whether to study programming or not ？

Today, combined with my personal research experience , Talk about my opinion .

Outline of this article ：

Research experience, share mind map

Textual research experience

During the period of university , I got a total of 6 A certificate related to programming , Among them is 5 I took the exam on my own initiative ,1 The certificate is arranged by the school .

Java OCA 8

The first certificate related to programming is OCA 8（Oracle Certified Associate）, yes Oracle The company launched a global IT Authoritative certification of personnel .

OCA The exam is divided into 3 A level ：OCA Certification Specialist 、OCP Certified Professional 、OCM Certified Master , There are many technical categories , such as Java、 database 、 Middleware etc. .

Classification of certification technologies

Certification website ：https://education.oracle.com/certification

I believe many students have never heard of this certification before , Then how did I know ？

In my sophomore year , I've just systematically reviewed Java Knowledge point , But I'm afraid I'm not strong enough , Just want to see if there's anything Java Certificate , Test your level by taking an exam , Leak filling .

So I searched all kinds of things on the Internet , I couldn't find anything at first , Then I thought ,Oracle The company did not acquire Java Well ？ Then you might as well go to their official website to see what certificates you can take , Their official certification should also be more professional and authoritative . Then I found OCA Java 8 authentication ：

Carefully read the certification requirements and examination contents , Find that it's exactly what you expect , So I decided to sign up .

But the registration fee for the research is still very expensive , My price was probably 1200 element , Basically far more than most of the domestic research fees . And must be paid in US dollars , So I had a special VISA card , Of course, you can also go directly to a treasure to find a payment agent .

Now the price has gone up again

Now that you have paid the registration fee , Be sure to be well prepared , I read the review materials specially for this exam during the winter vacation , Including official tutorials 、 The test sites sorted out by other students, etc . Because the test questions are in pure English , So most of the review materials are in English .

Probably reviewed 20 Days or so , It feels like learning again Java Basic knowledge of , But learned more details .

The official tutorial ：https://education.oracle.com/java/java-se/product_267

Now there are books specially published for this exam on the Internet , Like this one down here ：

The final exam is in the domestic agent Test Center , The exam environment is great , Is to lock you in a separate small room for machine test , There are dozens of questions , There are some concept questions , There are also some code reading topics . If you've really reviewed it , In fact, it is not difficult to pass , But because there are still some problems , So it's still difficult to get full marks , I was confident , But only nearly 90 Divide up （ Full marks 100, pass 65）.

Get the certificate

Software designer

The software designer is Soft exam A branch of intermediate , It is the computer technology and software technology qualification certificate issued by the Ministry of industry and information technology .

Soft test intermediate

Official website of soft test ：https://www.ruankao.org.cn

supposedly , I don't want to enter a state-owned enterprise , Why do you take this certificate ？

I applied for the exam in the last semester of my junior year , Because freshmen and sophomores learned a lot of basic computer knowledge , So I want to review as a whole . I just saw the certificate of software designer , I went to the Internet to find out , It is found that the scope of its examination is exactly the courses taught in the school , That's just not taking the test for nothing ！

So I handed it in 100 Multiple registration fees , Go to a treasure flower 1 Yuan bought a complete set of soft exam review videos and test papers over the years , Probably reviewed 3 Zhou , Read the video class and did it 10 Take a test paper , Knowledge points include ： programing language 、 Data structures and algorithms 、 cryptography 、 Software project management 、 Design patterns 、 Database design 、 operating system 、 Software engineering, etc .

When I finally went to the exam , I found that other candidates have basically worked , I don't see students like me . But it makes sense , Few people take the initiative to take the certificate , We basically take the test when we need it .

The exam is divided into two halves , There were many multiple-choice questions in the first half , Pay more attention to basic knowledge points ; There were many design questions in the second half , Pay more attention to software design and analysis ability .

Let's see a topic in the second half , Is to give you a scene , Let you use professional methods （ such as ER chart ） To analyze and design database systems ：

Soft test design questions

If you're not prepared , The problem is still difficult , Especially in the second half , There are code analysis questions and questions that let you write code . Code analysis questions usually give you a piece of code that uses some algorithm , Let you manually point out mistakes （ look for Bug） And fill in the blanks , If you don't understand the algorithm , It's almost cold . Handwritten code questions are generally combined with a design pattern , If you haven't used this design pattern , Or can't write it out , It's basically cold .

Finally, my score was not very high , But I also got the certificate, ha ha , I still have a sense of achievement （ Please ignore my photos ）：

PAT Class B & Class A

PAT（Programming Ability Test） It is a popular computer programming ability test in recent years , There are four levels ：

PAT examination syllabus

Official website ：https://www.patest.cn/

In general , Don't take the basic level , Directly from grade B or grade a , There's no need for the top .

I only heard about this exam during my sophomore summer vacation , Read the test content , It's kind of like ACM, It mainly exercises the ability of data structure and algorithm . When I was looking for my first internship, I was abused by algorithms , Is insisting on brushing the algorithm title , So I want to encourage myself to learn algorithms by taking this exam , By the way, check the level .

My algorithmic ability is average , In fact, I'm not confident , Anyway, the registration fee is only tens of dollars , Then you might as well try water from grade B first .

After signing up , I prepared 2 More than a month , In addition to insisting on brushing LeetCode outside , And specially went to PAT The official website of swiped the exercises they provided , By the way, I brushed the simple questions of Niuke , Keep hands on .

The test site is in Shanghai University , The test content is simple and rough , It's like OJ（Online Judge）, in total 4 - 5 Let's talk about the topic , Each topic gives you a scene 、 Sample input and target output , Let you design algorithms 、 Write code to solve the problem , And score according to the number of cases passed .

The difficulty of grade B is still relatively simple , Basically more than half LeetCode Simple questions plus 1 A medium question , The algorithm level of the students involved is generally not high （ Those with strong ability have started from grade a ）. I got grade B at that time 88 branch , At the top 5% 了 ：

PAT Class B certificate

After grade B , I went to apply for Grade A again , The difficulty of grade a questions is similar to that of algorithm questions in large factory interviews , in total 4 Problem , Basic is 1 A simple question + 3 A medium question . I was just completely right 2 Problem , The remaining two have ideas , But the time is not sure , It also ends in tears .

Although the result of the exam is not ideal , But at least it made me aware of my shortcomings , Go back to school and continue to roll .

Network Engineer

This certificate is embarrassing , I didn't take the test myself , But our school's network engineering major has a course called “ Enterprises IT Practical training ”.

The content of this course is to invite external training institutions to tell us some network knowledge , Finally, the successful certificate will be exchanged for credits .

Remember when I had to sit 1 - 2 An hour's subway to their company for class , Don't say anything about water , The key is the final exam , Tell us about the test site first , Then start the exam immediately , All original questions , There is no invigilator ！ Even the admission card at that time was wrong , What is called? “ Network Engineer Syndrome The test ”, Thieves are interesting .

Usually , The value and difficulty of a certificate are directly proportional , So the certificate of network engineer means , Not the professional certification of Huawei and Cisco , It's no use .

It is worth mentioning that , In this class of the school, we also got a certificate of entrepreneurial ability , Water can't , The entrepreneurial sand table system is all Bug.

CET 6

Last , Again, college students can basically take the exam National College English Test Band 4 and band 6 , I took the test together with the first echelon of the school in my freshman semester （ Freshmen take CET-4 ）, My grades are neither high nor low .

Tell the truth , This certificate has little effect on computer job hunting , It doesn't add a bonus to your resume . But if you want to work internationally or have certain requirements for English in the future , If you don't pass level four or six , Instead, it's subtracting items . Besides, , A job that really requires high English , A small CET-6 certificate is of little use .

But anyway , I suggest you study English well 、 Recite more words everyday . Although English is not good, you can learn programming , But good English can help you read code and English technical documents faster , Don't rely on automatic translation tools , Otherwise, you may get the wrong content ！

Should I research ？

After my own research experience , Answer your questions ： Should I research ？

Do things with a purpose, right , Before I choose whether to do the research or not , Will think first Two questions ：

1. What value can textual research bring to me ？
2. Verify whether the cost performance is high ？

The value of textual research

Review my original intention of textual research , Basically, it's not because this certificate contains high gold that I deliberately take the exam , But through textual research Motivate yourself to learn 、 Help yourself review 、 Test your learning results . If you pass the research, you can gain a sense of achievement , The failure of textual research is not terrible , Can find your own shortcomings , Leak filling . You can also write your certificate on your resume , Fill in a little , Reflect autonomy .

But tell the truth. , None of these certificates I took were difficult 、 General recognition , So for those looking for a job in the future Direct help is not much , I haven't been asked about the interview ; But in preparing for the exam , Inspired me to study independently and consolidated my knowledge points , It means a lot . After all, I paid the registration fee , It's not good to waste, right .

Research on cost performance

Some students said , More research , I'm sure I won't lose , What's the harm of having one more certificate in hand ？

But don't forget , In the process of textual research , You have to spend a lot of time , This time is used for other things , Like taking part in a competition 、 Do the project , Will it bring greater value ？

I suggest you consider these two points carefully , Then decide whether to research .

Which certificates are worth taking ？

In fact, I don't have many certificates , I can't give you a list of certificates worth taking .

But in conclusion , The preferred test certificate is Combine your career goals , Take the exam that is helpful for future development , Instead of being tested by others, I also test 、 Or for the sake of textual research . Also, we must choose the regular 、 Have a certain scale of certificates and examination sites , Don't take the examination of some fake certificates made up by black institutions , Beware of being cheated .

however , Students who intend to engage in development can try the certificates I have passed , I feel it's very helpful to me .

There are also many college students who are more concerned about the computer level II exam , For non professional classes （ Computer related major ） For my classmates , It's useful , Can learn some computer skills , Some enterprises may also have this requirement for recruitment , It can also add points to the settlement in Shanghai . But if you were Coban , Graduation is equivalent to achieving computer 4 Class level , There is absolutely no need to take this certificate .
