Band 4+: You were supposed to attend a friend's birthday party last weekend, but you didn't show up without any notice. Write a letter to your friend apologizing for your absence. You should include details about: - why you couldn't attend the party - why you didn't inform them beforehand - how you plan to make it up to them.

The letter attempts to address the task by apologizing for missing the party and providing a reason, but the response is unclear and contains irrelevant or inappropriate details. The reason for canceling is mentioned (a CNA class required by the supervisor), but the explanation is confusing. The letter also includes unrelated advice about the friend's mother and instructions about writing back, which detract from the main purpose. The plan to celebrate separately is mentioned (meeting at the writer's house due to the brother going abroad), but it is not clearly developed. To improve, focus on clearly explaining the scheduling conflict, express genuine regret about missing the celebration, and provide a specific, thoughtful plan to celebrate together. Avoid irrelevant or confusing details. The letter falls short of the required 150 words.

The letter lacks a clear and logical structure. The apology and reasons for missing the party are presented in a confusing manner, and the flow between ideas is disjointed. The paragraphing is not effectively managed, and the message is difficult to follow. To improve, organize your letter into clear paragraphs: one for the apology and reason, one for your feelings, and one for your plan to celebrate separately. Use linking words like 'because', 'however', and 'also' to connect your ideas smoothly.

The vocabulary used is limited and often inappropriate for the context. There are several errors in word choice and phrasing (e.g., 'apologizing you', 'CNA class', 'accept my sorry request'). The range of vocabulary is narrow, and the expressions are not natural or sophisticated. To improve, expand your vocabulary by learning common phrases for apologies and invitations. Use more precise words like 'apologize for', 'scheduling conflict', 'celebrate', and 'invite'. Practice using collocations naturally. Boost vocabulary complexity to elevate the overall score.

The letter contains numerous grammatical errors, including incorrect verb tenses, subject-verb agreement issues, and missing articles. Punctuation is often missing or misused, making the text hard to read. Sentence structures are mostly simple and repetitive. To improve, review basic grammar rules such as past tense usage (e.g., 'sent' instead of 'send'), subject-verb agreement (e.g., 'we attend' instead of 'we attend'), and article usage (e.g., 'a CNA class'). Practice writing more complex sentences with correct punctuation.
