The price of online courses in the market is basically around 5000, while offline courses are more expensive because of some other factors such as venue and labor. It is worthwhile to use this money to find or test a teacher who is suitable for Jiangsu college entrance examination. Of course, it is best to have ways to reduce the risk of trial and error, such as purchasing resources through some other channels.
Finally, I will send you a poem that you are still struggling on the way to the college entrance examination. I hope you can continue to go forward bravely with your dreams, not afraid of wind and rain, not afraid of failure:
Bodhi has no trees, and the mirror is not a stage. There was nothing, so there was no dust.
