The application "ビジネス英単語4002" is a comprehensive English vocabulary tool developed by Toshin Business School. Designed specifically for individuals aiming to enhance their business-related English skills, this app offers a structured and efficient way to learn essential words that are frequently used in professional settings. The app's goal is to help users master these words as quickly and thoroughly as possible. With a focus on real-world business communication, it includes words that are also commonly found in the TOEIC test, making it an ideal resource for both academic and professional development.

The app features 40 stages, each carefully organized based on the importance of the words. Starting from STAGE 01, users can progress through the content in a logical order, ensuring that they build a strong foundation before moving on to more advanced vocabulary. One unique aspect of this app is its approach to word derivation. For instance, the base word "manage" appears in STAGE 05, but its derivatives such as "manager" and "management" may appear in different stages. This method allows users to encounter related words multiple times, reinforcing their understanding and retention of the vocabulary.

An effective learning strategy recommended by the app involves consistent daily practice. Even just 10 minutes a day can make a significant difference. The app provides a variety of testing options, allowing users to choose between 10, 20, 50, or 100 questions per test. If time is limited, taking a short test with 10 questions is a great way to stay engaged. For those who want to learn faster, setting the test to 100 questions and completing it twice in a row can help identify words that need more attention. Once a word is marked as "unacquired," users can focus specifically on those areas and test again until they achieve mastery.

It's important to note that access to STAGES 03 through 40 requires a student ID and password from Toshin Business School. While STAGES 01 and 02 are available for trial, full access to the entire curriculum is reserved for enrolled students. This ensures that the content remains tailored to the needs of those actively pursuing business English education.

Additionally, upon first launching the app, audio data will automatically begin downloading. It is recommended to perform this download in a Wi-Fi environment, as poor signal conditions may cause the download to fail. The process typically takes around 10 minutes under good Wi-Fi conditions. This feature enhances the learning experience by providing pronunciation guidance, which is especially helpful for mastering difficult or unfamiliar words.
