1. "Including the US CPA exam in Japan" was changed to "including preparation for the US CPA exam in Japan." This clarifies that the school offers preparation for the exam, not the actual exam itself. The addition of "preparation for" makes the sentence more precise and accurate in describing the service offered.

2. "Our company policy on the website" was changed to "Our company policy regarding the website." The preposition "regarding" is more appropriate in this context as it better conveys the idea of a policy that relates to or concerns the website, rather than a policy that is physically on the website.

3. "We should not mislead about the difficulties" was expanded to "we should not mislead people about the difficulties." Adding "people" as the direct object of "mislead" makes the sentence more complete and clear. In English, it's often preferable to explicitly state who is being affected by an action, especially in formal or professional contexts.

4. "Japanese people well know" was corrected to "Japanese people are well aware of." This phrase is more idiomatic in English. "To be aware of" is commonly used to express knowledge or understanding of a situation, and it sounds more natural in this context than "well know."

5. "But not the US" was expanded to "but not those of the US." This addition creates a parallel structure with the previous clause and makes the comparison clearer. "Those of" refers back to the "exam difficulties," maintaining coherence in the sentence.

6. "Intentionally misleads people that" was changed to "intentionally misleads people into thinking that." The phrase "mislead into thinking" is a more common and precise way to express the idea of causing someone to believe something false. This construction better conveys the deliberate nature of the misinformation.

1. "You point out" was kept as is, rather than changing to "You've pointed out." In conversational English, it's acceptable to use the simple present tense here to refer to something just mentioned. It gives a sense of immediacy to the conversation.

2. "The duration period of the study" was revised to "the duration of the study period." In English, we typically say "duration of" rather than "duration period." The word "period" was moved to the end to create a more natural phrase. This structure is more commonly used when discussing time spans or lengths of time for activities.

3. "The education background" was corrected to "the educational background." The adjective form "educational" is more appropriate when describing the type of background. This is a common collocation in English when referring to someone's academic history or qualifications.

4. "The passed candidate" was changed to "successful candidates." The term "successful candidates" is more commonly used in English to refer to people who have passed an exam. Also, the plural form is used here as it's likely referring to multiple people who have passed the exam over time.

5. "Our rival company describes the cases of those" was slightly modified to "Our rival company describes cases of those." Removing "the" before "cases" makes the statement more general, implying that the rival company cherry-picks easy cases to describe, rather than referring to specific, known cases.

6. "It is not an honest way" was changed to "It is not an honest approach." The word "approach" is more suitable in this context, referring to the method or strategy the rival company is using. "Way" is more casual, while "approach" has a slightly more professional tone that fits well with the discussion of business practices.

1. "They are must-have items" was changed to "Those are must-have items." In English, when referring back to previously mentioned ideas or suggestions, we typically use the demonstrative pronoun "those" rather than the personal pronoun "they." "Those" more clearly links back to the specific ideas mentioned in the previous speaker's statement (FAQ page, search bar, etc.).

2. "When we set up company web pages" was modified to "when we set up our company web page." This correction addresses a few points:
  a) The addition of "our" before "company" makes the sentence more specific and personal to their company, which is appropriate in this context.
  b) "Web pages" was changed to "web page" (singular) because they are discussing setting up a specific page for FAQs, not multiple pages. Using the singular form is more consistent with the context of the conversation.

1. "We start it" was changed to "We should start this." The modal verb "should" is added to express recommendation or advice, which fits the context better. "This" replaces "it" to more clearly refer to the process of making adjustments to the website.

2. "Complete major FAQ contents" was modified to "complete the major FAQ contents." Adding the definite article "the" before "major FAQ contents" makes the phrase more specific, referring to the particular set of FAQs they plan to create.

3. "By 1st of April" was corrected to "by the 1st of April." In English, when referring to specific dates, we typically use "the" before the ordinal number (1st, 2nd, 3rd, etc.).

4. "If we get some other frequently asked questions" was changed to "If we get any other frequently asked questions." The use of "any" instead of "some" is more appropriate in this conditional statement, as it covers all possible additional questions they might receive.

5. "Add them on the web" was revised to "add them to the website." In English, we typically say "add to" rather than "add on" when talking about adding content to a website. Also, "website" is used instead of "web" for clarity and specificity.

1. "Our goal is not only sales volume" was expanded to "Our goal is not only to increase sales volume." Adding the infinitive "to increase" makes the sentence more complete and parallel with the second part of the comparison ("to introduce"). In English, when using "not only... but also" structure, it's important to maintain parallel construction between the two parts for clarity and proper grammar.
