As for which is better, offline learning and offline learning, I think each has its own advantages and disadvantages. Online courses can be studied at home, and parents can accompany their children to class without picking them up every day. I think offline courses are more suitable for younger children, because offline small class teaching can allow children to communicate face to face with teachers, and teachers can also guide children to build Lego and write interesting codes, so that the learning atmosphere is stronger and students can communicate with each other, which is better.
