It depends on your grades. From personal experience, the average student female teacher teaches well, because the female teacher is generally more careful than the male teacher, and usually grasps it more tightly than the male teacher, which is perfect for the average student and even the poor students. If you are an excellent top student, it is better for a male teacher to teach, because male teachers are generally clearer in thinking, more obvious in framework and better at explaining scientific problems (many problem-solving competitions are usually dominated by male teachers), which is undoubtedly more suitable for top students who want to hit high scores.
