高分子 化学(有機・無機)

From basics to difficult problems, an app that aims for a perfect score with high school chemistry polymers

You can get a perfect score for macromolecules!

951 questions about the range of chemical organic polymer compounds.

We have created a full-fledged app that covers the knowledge necessary for university entrance exams.

* We solve the latest entrance exam questions and constantly add necessary items.

Knowledge problems account for a greater proportion of macromolecules. Still, it is about half that I can remember compared to the range of organic compounds in the first half. Use this app as a score source for macromolecules.

I made questions based on the entrance exam questions as follows.

Kyoto University First semester 2016

Polysaccharides include glucose polymerized by β-1,4-glycosidic bond [A], synthesized from α-glucose in the animal body and stored in the liver and muscle [B], and starch.

[A] Cellulose [B] Glycogen

Problems and explanations within the app

Q. Glucose polymerized with β-1,4-glycosidic bond is [____]. A. Cellulose. From the β part of the β-1,4-glycosidic bond, we can see that the constituent unit is β-glucose.

Q. The substance that is synthesized from α-glucose in the animal body and stored in the liver and muscle is [____]. A. Glycogen. Glycogen is also called animal starch.

Kyoto University First semester 2016

Starch is a mixture of glucose polymerized with α-1,4-glycosidic bond [c] and glucose polymerized with α-1,4-glycosidic bond and α-1,6-glycosidic bond [d]. ..

[C] Amylose [D] Amylopectin

Problems and explanations within the app

Q. Of the starches, the substance in which glucose is polymerized by α-1,4-glycosidic bond is [____].

A. Amylose. It has no α-1,6-glycosidic bond.

Q. Of the starches, the substance in which glucose is polymerized by α-1,4-glycosidic bond and α-1,6-glycosidic bond is [____].

A. Amylopectin. For starch, only α-1,4-glycosidic bond is amylose. Amylopectin with α-1,6-glycosidic bond.

■ Extracted data (examined while solving entrance exam questions)

30 years from the University of Tokyo (University of Tokyo)

25 years of Kyoto University (Kyoto University)

More than 20 years at Tokyo Institute of Technology (Tokyo Institute of Technology)

20 years of Osaka University (Osaka University)

10 years of Nagoya University (Nagoya University)

Waseda / Keio Faculty of Science and Technology for 7 years

About 20 entrance exam questions for national medical universities

National National Chemistry Entrance Examination Questions for 2 years (about 100 times 2016-2017)

Center test 1990-2021 (main test and supplementary test)

Chemistry and basic chemistry textbooks (Keirinkan, Suken Shuppan, Tokyo Shoseki, etc.) (to match the current course)

* 2021 is also being added.

We checked and changed the titles, and added as much knowledge as possible that would lead to points in the entrance examination.

(Since it is sent from Twitter, please follow @kagaku_y_test)

I tried to match the arrangement as much as possible by comparing it with the textbook. It can also be used for daily learning according to the lesson. (* The order of items may differ depending on the textbook.)

I've included as many terms as possible that are only found in some textbooks. It covers almost all the terms in the textbook.

Although it is not frequent in the entrance examination, I also included a question to answer the names (Hideki Shirakawa, Ryoji Noyori, etc.) of the Nobel Prize winners (or candidates) featured in the textbooks. (Titles omitted)

The questions of checking the definition of words as needed are re-arranged immediately before and after to help with memory and comprehension.

Knowledge that can be used as a hint to guide the correct answer and knowledge that can be used as a hint to remember important items are also becoming problems.

(Since the explanation part is also a problem, if it is difficult to understand with just one question, please try to solve the problems before and after. If you have any questions, please ask on Twitter, email, blog comment, etc. App. There is a button on the settings page inside.)

○ Main usage

Basically, you will learn while solving the problem.

■ Confirmation test

Swipe left or right to see the next and previous issues. Tap to move on to the next question. Select an option until the answer is correct, and tap the option to proceed to the next question. You can also swipe to the next without answering correctly. In the confirmation test, I tried to do it manually instead of time so that I could proceed calmly and remember. A table of answers will be displayed at the end of the test.

■ Test 15

This is a mini test by category (by field). You can test in a narrow range.

We will solve each question with a time limit of 20 seconds, and finally we will answer each other. Select once for each question, and the correct and incorrect answers will be displayed when 15 questions are completed or when the end button is used to end halfway. The grades are scored, and the transition of the score is graphed so that you can see it visually. In Test 15, the range of questions will be narrowed down, so you will be able to get a high score in a relatively short period of time by doing it.

■ List

You can see a list of questions and answers in the range of questions by category (by field).

■ Score

You can see the report cards of the category (field) test 15 and the diagnostic test (25 questions).

■ Comprehensive diagnostic test, diagnostic test ABCD (25 questions)

Same format as test 15. By solving 25 questions from the entire range, you can check how much you remember the knowledge of polymer compounds in the entrance examination range. This is also solved in the same way as test 15. The grades are scored, and you can visually see the transition of the score in a graph.

Comprehensive diagnostic test range,

Diagnostic test A is macromolecules and sugars,

Diagnostic test B is an amino acid,

Diagnostic test C is synthetic resin,

It has become.

Aim for a high score by studying a combination of weakness reinforcement in Test 15, Review List, and My List.

■ Review list

The wrong problem is automatically added to the list for each menu page. If the test in the list is correct, it will be removed from the list. You can also manually select and delete it. You can also set the list to zero by clicking the "Reset Review List" button from the settings screen.

■ My list

From any screen after the test result for each menu page, you can select it with the Check button and add it to My List. You can reinforce your weaknesses by listing what you want to remember and focusing on it. To delete it from the list, select it from the Edit button (bottom right) and delete it. You can also set the list to zero by clicking the "Reset My List" button from the settings screen.

■ Settings

・ Ascending order or shuffle

You can choose from questions in order, shuffled questions, and so on.

Test 15 and 25 diagnostic tests will only be shuffled.

・ You can choose the number of questions from 10 questions, 20 questions, and a loop.

Test 15 and diagnostic test 25 questions are fixed at 15 and 25 questions, respectively.

・ Display of choices

No cover when select display. If you select Hide, you can hide the options immediately with a cover.

The choices are always displayed for Test 15 and Diagnostic Test 25 questions.

・ From the continuation or from the beginning

Click the button from the continuation to start from the continuation that was solved last time. You can go back to the first with the button from the beginning.

-Normal, Blue, Pink, Green are buttons to change the background color and text color.

The range of use can be expanded by using the app.

Five patterns are available for each of the four color schemes. Press the benzene ring mark on the upper right of the menu screen or setting screen to switch to 5 levels.

・ Reset review list, reset my list

When pressed, the items in the list will be zero.
