For the training courses from junior college to undergraduate, Chinese public education also has corresponding curriculum and teaching team. Using intelligent teaching system and providing online learning service can provide students with more comprehensive training and learning experience.
Personally, I think the college entrance examination training course of Chinese public education is still good. I suggest you choose according to your own conditions and needs. If you have a strong personal learning ability, then I think it is no problem to take the self-study exam, because the college entrance examination is not particularly complicated and there is relatively little competition, so it is relatively easy to take the exam. I hope my answer can help you.
