Test results can be measured from Pre A-1 to B2 High in the CEFR standard. For example, you may have measured your ability to listen and read English, but you have never diagnosed whether you can actually speak English properly. Or, you may be worried about communicating in English. To address these issues, PROGOS was created a test to measure speaking ability based on practical business English conversation situations. The content of the PROGOS test is focused on English used in business situations, such as interviewing, expressing opinions, making presentations, and interacting with people to get work done. This test assesses not only your knowledge of English, but also your ability to communicate in a practical way. The test results are displayed with extensive feedback to help you with your continued studies. This app stores your test history, so it's a great way to see how your skills improve over time. The test takes about 20 minutes, and the test results are scored in around2 minutes after the test is completed. This app allows you to conveniently check your business English speaking skills! ■Overall evaluation of PROGOS The Common European Framework of References for Languages (CEFR) places a great deal of importance on "What can I do with the language?". Therefore, the overall evaluation of PROGOS takes into account the six qualities of speech (range of vocabulary, accuracy, fluency, interaction, coherence, and phonology) as well as the degree to which communicative objectives are achieved. It is not a simple sum of vocabulary and pronunciation assessments, but a measure of practical communication skills. ■Analytical Evaluation 6 analytical aspects defined by the CEFR. (1) Range Knowledge of grammar, sentence structures, vocabulary, and phrases. (2) Accuracy Correct use of grammar, vocabulary, etc. (3) Fluency Fluent and smooth speaking. (4) Interaction Ability to start, end and / or maintain a conversation. (5) Coherence Organization of speech and logic. (6)Phonology Intelligible pronunciation, intonation and stress.

Each correction comes with an explanation, so you can understand why a change is needed and develop your writing skills. When you're unsure about an expression, you can ask AI directly. Ask questions about your diary, such as "Does this sound natural?", "What's the difference between 'the' and 'a'?", or "How can I say this more casually?"

Practice reducing repeated mistakes and reinforcing what you've learned. ■ Look Back With Weekly Reports Review your diary entries, AI chats, words used, and words used for the first time each week.
