Thank you indeed for writing this letter.
Task Achievement (TA): The candidate has addressed all three bullet points required by the task:
Described the problem with the equipment.
Explained what happened when they phoned the shop.
Stated what they would like the manager to do.
However, the request to receive both a full refund and a replacement mixer may be seen as an unrealistic expectation, which can slightly affect the score as it might not completely align with what might be typically expected in such a situation.
Coherence and Cohesion (CC):
The letter is logically organized and progresses from the introduction of the issue to the requested resolution. However, there are issues with the flow and connectivity:
Overuse of "and" which can make sentences run on and impact readability.
Some awkward phrasing ("the person, who I have talked to,") disrupts the natural flow of text.
Transitional phrases and a clearer structure could improve the score in this area.
Lexical Resource (LR):
The vocabulary is generally appropriate with terms correctly used ("fully refunded", "return policies"). However, the range is somewhat limited and there are some inaccuracies:
Repetition of certain words ("bought", "mixer") without attempting synonyms or rephrasing.
Inappropriate or awkward collocations ("plugged to the electricity", "free mixer").
Variety in vocabulary and more precise language use would enhance the score.
Grammatical Range and Accuracy (GRA)
The grammar shows a mix of simple and complex structures. However, there are several errors:
Incorrect tense usage ("I have bought" should be "I bought").
Misuse of articles ("the mixer" could simply be "my mixer").
Misplaced commas and awkward construction in relative clauses ("The person, who I have talked to," should be "The person I talked to").
More accurate and varied grammatical constructions would be necessary for a higher score.
Overall
The candidate should aim to use a wider range of vocabulary and grammar structures, improve the natural flow of information, and ensure realism in their requests to increase their score.
