Band 6+: Can you help me? I did badly in my exams last year and I would like to be better prepared this time. Do you have any suggestions on how I can avoid the same thing from happening again? Write back soon, Hannah Write your letter.

The letter addresses all parts of the task by providing relevant suggestions to help the friend prepare for exams. The tone is appropriate for a letter to a friend, and the ideas are logically organized. To improve and reach a higher score, you could expand more on the suggestions to provide more depth. For example, instead of just mentioning organization, you could suggest a specific tool like a planner or a digital app. Additionally, ensure that your phrasing is completely natural; for instance, 'understand the subject of the exam letter' is slightly awkward and could be replaced with 'understand the exam material more thoroughly'. The letter falls short of the required 150 words.

The letter is logically organized and follows a clear progression from the opening to the closing. You have used cohesive devices such as 'To start off', 'In addition', and 'In this way' effectively to link your ideas. However, the transition between the suggestion of studying early and the final sentence could be smoother. To improve, ensure that every sentence flows naturally into the next to avoid a slightly 'list-like' feel.

You have used a good range of vocabulary appropriate for a friendly letter, such as 'well structured', 'straightforward', and 'key suggestion'. There are a few minor errors in word choice and usage, such as 'suggestion' instead of the plural 'suggestions' and the confusing phrase 'subject of the exam letter'. To reach a higher band, try to use more sophisticated collocations and ensure that your word choices precisely convey your intended meaning.

You demonstrate a good mix of simple and complex sentence structures, such as the use of 'not only... but also'. Most sentences are clear and easy to understand. However, there are some grammatical inaccuracies, particularly regarding noun number (singular vs. plural) and some awkward phrasing in the third paragraph. Focus on refining your use of articles and ensuring subject-verb agreement to improve overall accuracy.
