the article is organised to some limit since the writer has ordered the events according to time from 09:00 am to 05:00 pm , i assumed the time since the writer is talking about a regular day at work.
the use of articles is not bad except for one mistake (have a coffee) where he can say (have coffee) or (have a cup of coffee) .
the use of prepositions is mainly good.
he has a mistake in the possessive pronoun (his boos) he should have written (her boss) because he is talking about a female's day not about the boss.
the use of vocabulary is not very bad and the building of phrases is good but he should have written (take a break) instead of (make a break) and (responds) instead of (correspondence).
i see the spelling and the word order is fine except the spelling of the word (coffe) should be (coffee) and not adding the (third person s) to verbs like (she carry on, she start , she make , she go on , she keep)
i think the writer is combining the present continuous with the present simple, i think since this is a daily activity for the woman that repeats almost everyday , he should use present simple more often.
the student's strength is having little spelling mistakes and good use of articles and prepositions and ordering events.
the student's weakness is mixing tenses and not including details like time.
i would recommend this student to review some grammar of how to use tenses and to differentiate between when to use present continuous and when to use present simple , he can do that by describing his normal day activities and then describing other person activities and noticing the s that should be added to a verb when speaking about a third person, he can do that using present simple then present continuous then he can use the past tense and so on.
