West China Medical Center doesn't seem to have it. I have never heard of such a college remedial class. On the contrary, online remedial classes are really good, but they are very expensive. A set of 500 medical practitioners is still relatively expensive. It is inconvenient without broadband, and it is not cost-effective to watch it in internet cafes. Last year, I enrolled in a remedial class for medical practitioners, and now I have audio and word notes at hand. If you have listened to online courses, you know that videos are useless. Useful are word notes and audio. The effect is really good. Listen carefully, you can firmly remember, because they are all memory methods of various diseases, some formulas are fluent, and personal feelings are really good. Do the exercises again, and there will be no problem after that. Through this thing, the personal feeling is illusory, because as long as you review well, you will get something. Just hearing a number is a high pass rate. If you don't review well, you will still have zero pass rate. Those are just their slogans.
