This is an obvious point but also the most important one. A computer, a good Internet connection and a headset are what you will need to take classes online. A web camera is also pretty important. Make sure that your computer is turned on, that everything is plugged in correctly and that you have tested the connection. Doing this before the class means that you will be ready when the lesson starts

Take the classes somewhere quiet.

      小题3:     

When grammar or anything else is being taught, make sure that you understand it. You won’t need to practice it at this time; just make sure that everything is clear. If you don’t understand what is being taught, ask your teacher to explain it again. Your teacher will be more than happy to deal with whatever puzzles you.

Practice speaking English.
