Long school hours
First of all, it depends on the time when they run schools. The sooner they do it, the greater their interests will be. They can continue to operate in the competition of many peers for more than ten years, which proves that they are very powerful.
Network evaluation
Secondly, it depends on online evaluation. Who doesn't surf the Internet now? The internet can be regarded as an exit, boasting and swearing are all said online, which is particularly practical for me. There is industry propaganda and trampling on each other, but it doesn't matter. If it is really good or bad, the general trend of comments is clear at a glance. In the evaluation, you can also get a preliminary understanding of institutional information, such as efficiency, attitude, and the authenticity of the test certificate.
Self-study institutions are not recommended to choose.
Self-taught exams are more difficult. It is not recommended that busy people choose self-taught exams to improve their academic qualifications, so the institutions that do self-taught exams suggest passing them directly.
Chengkao/RTVU
The entrance examination is directly registered online in Shanghai Education Examinations Institute, and RTVU is registered in Shanghai RTVU (now Shanghai Open University), which can be run by itself. However, there is only one chance to register for the entrance exam a year, and you need to take the national unified exam. But RTVU's words are considered to have low gold content (though not).
