How to write the beginning of exam reflection?

Time seems to pass quickly, but in a blink of an eye, the semester has already passed. I listened carefully to the sound of the clock, as if I felt the flow of time and the passage of life. Time seems to be a sea, and I seem to be the one who is boating in the sea. I grow and progress slowly in the sea. When I first came to Shanghai, I didn't find the knack of rowing for a long time because I didn't adapt to life at sea, so I rowed better than others. It took me a sixth of the time to realize that boating in the sea is so comfortable, although it takes a lot of effort, although I need to learn the skills and accuracy of boating slowly. But I still feel very happy. Because in the process of this inquiry, I found a kind of happiness beyond myself. Isn't boating just like studying? Getting good grades requires an adaptation process. But think about it, am I really just because I don't adapt? I think there is this reason, but is it entirely because of it? I don't think so! Many times, the knowledge that should have been learned that day was delayed because of the uncertainty of one's will and the lack of a clear goal. Putting off studying until the weekend will lead to a lot of things that should be studied without time to review. Finally, some half-baked things are not solid, and the exam will naturally expose these shortcomings. Then, since we know where our problems are, we should correct and improve them. From now on, as long as we can learn well and review and consolidate what we learned that day every day, we will have enough time to review other subjects at the weekend to ensure foolproof. We will be confident when we take the exam, and we are fearless no matter how we take the exam. Also set yourself a goal, neither too high nor too low; If it is too high, it will be discouraged if it does not exceed this goal; If it is too low, it is too easy to exceed your own standards, and it will not exceed your own pleasure. Therefore, it is also essential to set goals for yourself. I continue to go boating in the ocean of learning, slowly accumulate the experience I found in the process of boating, and try my best to get familiar with and master it. In the accumulation of this knowledge, I feel the flow of time and the passage of life. In this drifting sea, I learned to learn and reflect.
