I don't think this is a problem. You can study hard from now on. The harder you work, the better. Of course, you should combine work and rest, study and play. It's good to get into any place if you are admitted. You still have a chance to study hard in high school. How can I get into my favorite school by stepping on the score line during the exam?
Generally speaking, enrollment is also greatly influenced by the number of applicants in that year. This is for reference only.
