Now, studying online has become a common way of learning. The biggest difference between studying online and studying in school is that our teachers can't ▲ us all the time, so we should be able to control ourselves. I didn't know this at first. During our online classes, I often got distracted by my mobile phone.
For this reason, I didn't do well in the midterm exam. At that time, I realized that I had to do something to improve my online study habits, so I made up my mind to concentrate (集中注 意力) on the online classes. Finally, I made much progress in the final exam.
Now I want to offer you some ways I used to improve my learning during the online classes. Firstly, make a list of what you should do and what you shouldn't do. Try your best to follow it. Don't set your aims too high at first, because proper aims can help you to make the list work. Secondly, keep your mobile phones out of your reach when you study. Give them to your parents if necessary. Thirdly, make efforts to review and overcome your shortcomings in the process of review. You can ask your teachers for help or work with your classmates.
In general, we should stick to keeping good learning habits all the time. I hope that all students can study better both online and offline.
