Can oral English be written directly in writing? For example, sat composition, ibt composition, school examination and so on.

Hello, I'm glad to answer your question!

You'd better not. There are a lot of words and expressions in spoken English, and the exams you take are all academic exams. The examiner asks you to express an idea in informal vocabulary, grammar and sentence patterns. In spoken English, there will be omissions of sentence elements, even deliberate grammatical errors, which will not appear in the writing test. Since the exam is divided into writing and speaking, it shows that the focus of the two exams is different. Try to explain your point of view in the correct way in the writing exam.

I hope my answer is helpful to you, and I wish you success!
