Writing Feedback / IELTS writing practice test review - enquiries received by the Tourist Information Office [3]

Actually, your opening is too general, you need to specify it clearly. Which kinds of inquiries include???
Review grammar in the Overall sentences
Review meaning of proportion

Writing Feedback / Task2: The benefits and disadvantages of working from home [7]

Around the word - in any part of the word (good phrase for you to apply)
Many parents are working FROM HOME and children are beginning to study FROM HOME (repetition) - A number of parents and students had an upward trend to work from home

Moreover, the innovation of education of studying at home rather than learn at school like a traditional way will probably change significantly the way student approach the lessons (mistakes in grammar)

I think you should review the structure of Task 2 Writing, on youtube videos, for example, as well as enhance your grammar
