I bought a BBK point reader, a student computer and a reader that can store videos at home. Personally, except for the video reader, everything was interesting at first. After the novelty, I was lured back by my mother to use it. If you use a video reader now, it is still new. What you don't understand in class is very useful. If I teach early, it may be similar to the student computer I use together. At first, I used it every day. Later, my mother set the study time in the computer, every day.
