First Task

What experience that I have while I Having teach or taught by friends ?

My experience is I was confuse about the physics test because of my teacher taught with just only a several time go to the class and then say that we will have a test next week. Me and my friend was confuse because of that. Then we decided to study together. We study at my friends home because it's more efficient than study at school. We sudy about the concept about how that thing work. And we study about the formula that we need for the test next week. We don't even know about why the formula was like that. And even that formula is confusing both of us. And in the end, we chose to study even if we can't.
While we still think about how we study, my friend have an idea that how about if we have a course in my teacher. That's the end of our first meeting.
And at the second meeting, we decided to gather together at his course place.The teacher was so kind. And he can make us understand about the formula and about the concept how that thing work. We continue to study together by work a questions that have a relation with our test. Then, his teacher give both of us a question about the concept and about the formula, so he will not doubt us if we say that we understand about the formula and the concept. The question about the concept we work by ourself, but the question about the formula, we work it together. We remind about the formula because we work together, so if my friend forgot the formula, I remind him, if I forget the formula, he remind me, so we reminding the formula each other.
