How to take the second level of computer science???

I heard the teacher say that the second level of computer science seems to focus on C language programming, and it is difficult to learn by myself, and I don't understand what the teacher says, maybe it's my IQ problem.

C language is relatively easy, if you only want to take the second level certificate, it doesn't matter what information, now it's all the same (are mutual reference), first find a book, you must be perseverant, read more of this book in a short period of time (strengthened), when reading the book, pay special attention to the column, after reading the column, you will do it again next to the column, and then close the book and do it again, and then you have to summarize and find some topics to do after you read several structures and functions of c. After that, when it comes to arrays, pointers, data structures, files, etc., you need to find more classic C columns for more analysis. It is not advisable to do a lot of questions.

Combined with my own situation, my humble opinion hopes to help you.

1. Written test

In terms of the written test, I think the first thing to do is to clarify the basic concepts, and don't swallow dates. Many friends are in a hurry to read books, and I don't think it's advisable to set yourself a few pages a day to read. For relatively simple places, such as C language background, advantages and operation processes, and other conceptual things, you can write them down after familiarizing yourself with them, and you will naturally understand them slowly in the future.

For example, any C language statement must add a semicolon at the end, the introduction of pointer concepts, the call of functions, etc., these concepts are easy to ignore or difficult to understand for beginners, and it is worth spending more time in this regard.

After understanding the knowledge in the textbook, it is time for intensive training. At this time, you need to do some of the questions appropriately, use the workbook that goes with the textbook, and focus on reviewing functions, arrays, and pointers. These three major areas of content are the most important in both the written and computer-based exams.

In addition, it is important to have a good grasp of conditional statements and circular statements, as most of the questions contain these two types of statements.

If you finish it in a hurry, it is likely that you will do the questions again with the previous mindset when you come back to check, and it will not have the effect of checking.

Finally, I would like to say a little about the basic knowledge of computers, this part covers a wide range of knowledge, and the required knowledge is relatively comprehensive, there are no typical topics, and there is no trick to review, and it can only rely on the accumulation of time. When you are doing the questions in this part, you should be careful not to go beyond the scope of the outline.

Second, get on the plane

My views on the computer may not be quite the same as those of some of my friends. Some people think that the computer-based test is a random selection of questions, and there is an element of luck, but I think there are still skills to be found.

The first is to strengthen the hands-on exercises. You will do the same question on the test paper, but not necessarily on the computer. This is due to the fact that you have less hands-on operations, resulting in an unfamiliar environment and poor ability to deal with actual errors.

The second is to pay attention to the rules. The computer-based questions of Level 2C are scored by the computer, so there are many things that deserve our attention. For correcting this kind of question, there are generally 2 or 3 errors, all of which start with "*found***."

For the bottom of the logo, the change is not big, here do not break the original program structure, especially pay attention to do not add blank lines. Since the computer finds a specified number of lines and compares them when scoring, if you add any blank lines in the program, the computer will not match the number and will naturally not be able to score. Compared with correcting mistakes, programming questions are more flexible, so you should read the questions carefully, and you must not use the functions that are not used, and do not simply save trouble.

Remember to save it when you're done.

Computer Level 2 Exam Process:

Step 1: Print the Computer Level 2 Admission Ticket.

Step 2: Arrive at the computer level 2 test location at the scheduled time to take the exam.

Step 3: Wait for the test and start drawing numbers (i.e. the serial number of your own test computer) at the same time.

Notes on Computer Level 2 Exam:

1. What to bring to the test Candidates need to bring their ID cards, admission tickets and body temperature monitoring forms to enter the examination room when taking the computer level 2 test.

2. Arrange the answering time reasonably.

Preparation for the exam:1Don't memorize by rote.

2.Pay attention to the use of mock test software.
