[Examination Report] Python 3 Engineer Certified Data Analysis Exam

Introduction

This article is a brief record of the ** Python 3 Engineer Certification Data Analysis Exam ** that you passed the other day.

I think that the general information about this exam has been enriched, so here ** personal impressions about the exam ** (including difficulty level) and helped during the preparation process ** (free) I would like to focus on the practice test **.

We hope that it will be of some help to those who are going to take the test.

Official information

――Please check this ** Official Site ** for the exam. -** Examination method ** ・ ** Exam outline ** ・ ** Exam range and question ratio ** etc. are listed.

Impressions of the exam

――As for the difficulty level, I thought that the mock exam described later would be a good reference. If you consistently exceed 700 points (out of 1000 points) in the mock exam, you have a good chance of passing. After all, I thought that the mock exam was more difficult as an overall impression.

--For the main teaching material ** "Textbook for new data analysis using Python" ** (Shoeisha), --If you are new to both Python and programming, I thought that preparing for this material would be the shortest path in terms of qualification. ――However, I didn't buy this material because I was already studying with other materials. Also, there was no particular inconvenience. In addition, some of the studies on the G test that I did in the past were useful.

--The pass / fail result will be displayed on the monitor after the test is completed. In addition, you will receive a separate paper with the score and the score rate for each field printed on it. Regarding this point, it is a pity that we cannot confirm the incorrect answer after the test. It only takes 5 minutes immediately after the exam, so I thought it would be a more educational and meaningful exam for the examinees if there was a session where they could look back.

Free practice exam

The following two practice tests are introduced on the official website. I also used this and it was very helpful.

DIVE INTO EXAM

This is the first Mock exam site.

① Overall features

――You can take the exam multiple times. (I didn't know this at first glance.) In other words, it is not necessary to leave the practice test here as the "total finish" just before the main test. Rather, I think it is better to take the test as many times as necessary, fix it each time, and use it in a style that aims to stably exceed the passing score.

――In addition, in the second and subsequent exams, the questions that have already appeared and the questions that have newly appeared will be mixed. (On this point, I thought that it would be possible to learn more efficiently if the questions that were answered correctly in the past are not asked at all from the next time onward, or if there is a mechanism that asks questions randomly at low frequency. Let me give you a selfish opinion.)

――After taking the exam, you can check the questions, scoring results, and correct answers on the web. (However, it is not possible to confirm what happened to the options for each question later. Therefore, if you intend to carefully look back and correct after the mock exam, you can select some options during the exam each time. You need to copy it.)

――If you take the test multiple times, the transition of points will be displayed.

――The score will be adjusted according to the actual score (out of 1000 points).

② Characteristics of questions

--The pandas data frame and matplotlib plot are displayed as images, and there are many questions about coding. I also thought that this type of question was visually easy to understand and was practical beyond the framework of the exam. However, there was no such question in this exam.

――Nevertheless, the overall tendency of the questions was almost the same as in this exam, in terms of the questions asked.

――In addition, I think that the difficulty level of the mock exam was slightly more difficult than that of the main exam.

PRIME STUDY

This is another Mock Test Site.

① Overall features

--There are 3 exams.

――In addition, not all the problems are new each time, and there are not a few problems of "reuse" such as replacing some words of the previous problem. (This is a story that also affects learning plans and estimates, and taking the mock exam here three times does not simply triple your experience points.)

――After taking the exam, you will receive an email with questions, scoring results, your own answers and correct answers. (However, it is not possible to confirm what happened to the options for each question later. Therefore, if you intend to carefully look back and correct after the mock exam, you can select some options during the exam each time. You need to copy it.)

――You can take the test again even if you took the test once. (This is useful when you want to solve the exact same problem again, or when you want to check the problem you are interested in later.)

――This mock exam is scored on a scale of 100 points, but since the number of questions is the same as this exam, you can simply multiply the score by 10 when converting.

② Characteristics of questions

――I felt that there are many topics and types that are included in the options, especially in word problems. (I think this is the result of trying to improve the comprehensiveness of the mock exam with a limited number of questions. However, in the questions of this exam, the options were organized within a slightly narrower range. )

――Although it is related to the above, I feel that the difficulty level is higher than this exam, or that the style of questions is slightly different (for beginners) in a maniac direction.

――Still, for beginners who can afford a little, I think that there is no loss in doing it beyond the framework of this exam.

Summary

Based on the impressions of using the mock exam, the ** PRIME STUDY ** mock exam is ** learning ** in the first half of the preparation period, and the ** DIVE INTO EXAM ** mock exam is ** practice **. It is also possible to use it in the latter half of the preparation period.

*** However, the above is my personal opinion, and it is expected that the contents of this test and the mock test will be updated in the future, so please refer to it as one idea at the time of writing this article. I would appreciate it if you could. ** **

Thank you for reading to the end!
