Of course, many platforms need money. Litchi micro-class, thousand chat platform, Tencent classroom and so on. Some study and think, some study in New Oriental, and some are tutored by apes. You will find that those online class platforms are getting bigger and bigger. More and more. Quality, there will always be good, of course, there will always be bad, first of all, you have to have the ability to judge whether this course is good or not. There are many standards for good or bad. First of all, the content of this course is good or not. What suits you is the most important thing. If you get good grades, you talk about some basic things, and what you listen to is of little significance. If you have a poor foundation, it doesn't make much sense to talk about those so-called finale questions, so different courses have different effects.
This requires careful choice. Different platforms also have different teachers and different classes. But in any case, I personally think that the platform is not important, what matters is the heart.
One more thing, of course: money is very important. Courses on the same platform all need money. We have a belief that what we can do in Bai Piao is Bai Piao. Look at us in Zhihu, and it's good to share. Of course, I'm not saying that my class is good, I'm just saying that many excellent bloggers share excellent content. At least I saw many excellent ones on the platform. I am really ashamed to read their update. There are many professionals with strong professional ability who speak very well. And many of them are systematic. So what I want to say is that you can search Bai Piao's network resources on multiple platforms as much as possible. You can always find what you want.
In other words, if you can find a free class with good quality, you just need to hold your thighs tight, and if appropriate, just follow suit.
