it's okay. it's not too late if you change to grade 2. Just practice more, but if you apply for those conservatories, it is estimated that there is little hope. It is ok to take some ordinary two books, or it depends on your efforts. The ordinary college entrance examination is not too picky. You can do it as long as you work hard. It's not a big deal. Some of my friends only studied for half a year before they got in. We should also pay attention to the written part!

good luck! O(∩_∩)o...
