I suggest liberal arts. Although some schools now accept both arts and sciences when enrolling students, the enrollment quota for liberal arts is more than that for science. Of course, there are more students in liberal arts.
Also, when you study after taking the school exam, your scores in the liberal arts program will improve quickly. For science comprehensive exams, the question types are very flexible and you have to do a lot of exercises. As long as you know the basics of liberal arts, it will be easier to score more papers.
If you are a girl, you should choose liberal arts.
