useful advices

Today the half of our classmates arrived to the classroom fifteen minutes after the lesson had begun. Carlos was the secretary of the day, but he also came late, so the teacher had to start the lesson. After the usual tasks, today we did not get any new activity, but the teacher told about the common mistakes, we have made before. This way, now we have to improve our exercises, we finished before. I just realized, that I have forgotten writing a conclusion about the activities, I have done, several times. But it wasn't the only one mistake I made, I am sure, so I have to spy on them, because now I don't know, which one of my activities is right and which one is wrong. So this weekend I am going to develop my statements, I have uploaded before and write them in a better way. In the end of the lesson, we get a few minutes to finish the activity from yesterday, but the half of our group missed the opportunity to work with us today and we (me, János and Carlos) were not motivated enough, so the task will be finished in the weekend by us, but of course we improved it as much, as we could.
