Recently we have had a discussion about whether it is a proper way to study in the 10-minute break or not..
Recently we have had a discussion about whether it is a proper way to study in the 10-minute break or not. Some students believe that it can help them save time to do more exercises. So that they are able to get rapid progress. But I hold the opposite opinion. Firstly, after 40minutes' class we have been tired including our body and brain. Therefore certainly we need to have a short break. Secondly, we should get ready for the next class rather than do some exercises. The last but not least, it is a chance for us to go to the washroom.
