I wrote exactly 300 words in my TOEFL writing test second essay! It just reaches the minimum word count of so-called qualified essay.
In fact, I have done little preparation for my TOEFL test. From time to time, I think I need to do something about my TOEFL test, but I just don't want to do anything around it. So, I didn't use any strategy during the test, and spoke and wrote without any so-called pattern. I don't know what kind of score I might get for doing this. Anyway, it will just reflect my true level, I think.
