My study situation is similar to yours. In the top ten rows of my class, liberal arts is better, but in the exam, it is much more difficult to get a score for liberal arts and a score for non-science! I think you should test A first; The level of arts and sciences in school B, because the second year of high school should be divided into subjects! Secondly, you should study arts and sciences steadily, and never be partial to your subjects! I don't think it's a good idea for you to become a member of school B. Learning is your own business, and it's right to find a school that suits you. I still hope you go to the ideal school. It doesn't matter if there are dozens less. It's not too late to work hard. It is better to do more questions in science, recite more in liberal arts, and grasp composition.
