Cheating in school

Your sentence is grammatically correct but we can also just say "junior high".

One day, I was picked by the gym teacher (to represent the school in sports...? To participate in the school carnival?) as I was the tallest in class.

I was not good at either gym or school study.(or "I was neither athletically nor scholastically inclined.")

I just wasn't interested in anything at that age.

I was put in high jump, long jump and sprint/long distance.

There's a common stereotype that if you're good at gym, then your school marks for won't be as good. I fell into this misconception and focused only on sports, ignoring other school work.

One day, we had a history quiz.

I did not study because I believed I wouldn't be able to do well anyway.

So my group of friends, who were good at gym as well, and did not want to study, suggested we cheat. I agreed. (sorry, not sure what you were trying to say)

We sat on our chairs and got ready for the quiz.

I could feel the beads of perspiration forming on my trembling hands.

Our desks are made of wood and has a drawer underneath.

I put my history book into the drawer and whenever I didn't know the answer, I'd take the book out and checked.

When I heard the teacher call my name, I felt like my heart almost jumped out of my mouth.

"What are you doing?" my teacher asked me seriously.

My mind drew a blank.

I thought, "How did she see the book?" She read my mind, telling me that: "You are not good at cheating so you should check your desk before you try to cheat." It turns out that my drawer was missing a side, and so that was how my teacher saw me taking the book out.

My teacher forgave me because she knew I wasn't really a bad student. This marked my first and last time cheating in school.

That was when I was in Junior High School a long time ago. Your original sentence was grammatically correct, but it was "open-ended," since it began with a reference word, "that," without anything to refer to. This may be a stylistic approach, but it is a little confusing to the reader.

One day I was picked up selected by the gym teacher as because I was taller than others in at the class.

I was not good at gym, nor was I also not perfect at school study.

At that age, I just was not interesting interested in anything when I was that ages.

They The gym teacher put me in high jump, long jump and running in race. In English, if you are running in gym class it is always a race, either against another person or yourself and the clock.

Most of people know believe if you good at gym, that means your school marks is are not good.(I do not know how I describe this situation!!) So I follow the group of in gym just to focus on gym, not in the while keeping up with my school works.

One day, we have had a quiz of in history.

I did not study because I believed I am was a gymast, who would not do well in school.

So, one of my classmates in our group of in gym, who does not want to study either, at suggested that we can could cheat at on this quiz. (I attached the photo about of the desk, but maybe I didn't describe not it right, could you correct.) I do not know whether how I said yes or no, but, actually, I did.

I can feel my hand palms all wet and a little bit shakey. When one is nervous one's palms often become moist.

Our desks are made of wood, has a drawer, and is covered on two sides.

I put my history book into the drawer, and when I do did not know the answer to a that question, I take took the book out between my legs and the drawer.

I wonder think,"How does she see it?" She thinks knows what I am thinking, and gave told me: an answer, "You are not good at cheating; you should check your desk before you cheat in the quiz." My desk does did not have a cover on the left side, of cover so why my teacher saw my book, in and out of the desk.

My teacher forgot about it me because I am not really a bad student, so but this is my first and also my last cheating in school.
