Hang, your essay suffers from a lack of clarity in explanation. It is not coherent nor cohesive and causes the reader undue stress while reading it. Even after multiple readings, it is still difficult for the reader to assess what the meaning of your paragraphs are. An example of a confusing paragraph from this essay is:
No matter where contender understands,(...) , if his answer wrong.
This is one of the more extremely confusing presentations in your essay that begs the reader to ask you to explain what you mean. I think you are confused about what the purpose of the essay is. When you are asked about the pen and paper test, this is similar to an online test. When you are asked to do an oral report or respond to an oral question and answer exam, that is a different form of exam taking. Pen and paper is highly similar to online testing because computations are still required at least during the exam itself. Whether they submit their computations or not is up to the teacher or exam moderator.
In this particular paragraph, I believe you just miswrote the sentence, which made is unintelligible to the reader:
Some students have the rote learning phenomenon.
What is a rote learning?
I believe that your problem is that you are thinking in your native tongue and then translating it word for word to English without considering that what has a correct mean in your mother language may not have the same meaning in the English language. You need to practice thinking in English aside from writing in English. Thinking in English is what will help your work become more coherent to the reader and help you to improve your overall essay score.
