The one above, it's just nonsense. As far as ordinary grades are concerned, liberal arts are indeed easier to score, but high scores are not so easy. Arts and sciences cultivate talents with different ways of thinking and different aspects. For political history, reciting the two subjects is far from trivial. A lot of reciting is indeed the foundation, but understanding memory is very important, and it is useless without understanding memory. Politics needs the ability of logical thinking, induction and summary, and being familiar with the knowledge framework is the basis of doing the problem. History needs the ability to extract information, summarize and master events in every time and space in history, which is the basis of doing the problem. These abilities need to be cultivated, which can not be provided by the knowledge in the counseling book, nor can they be improved in a short time. Moreover, there is no need to cram for the basic recitation, and it depends entirely on consciousness. I think this is the reason why there is so little political history of extracurricular tutoring.
