As long as you can get more than three C's, you can apply for one. Undergraduate courses, namely 2A and 2B, need two C's. The junior college needs at least C, and there is also a grade exam, even if it is not ideal for the first time, you can retake it.

As far as the college entrance examination is concerned, it should have no influence if there are many academic level test scores, but it will have a great influence if there are few, because most provinces and cities will stipulate which level of C or above is necessary. Basically, one book needs at least all C's, two books need at least two C's, and three books need at least 1 C.
