According to the actual arrangement, the second-year course will not have much time to invest, mainly in physics and chemistry, and others just need to continue learning according to the rhythm of last semester.
Learning should have a main line or your own learning habits, which may only suit you and be the most efficient for you, so it is more effective to form your own habits as soon as possible. In the near future, you can make arrangements and try to add a dulcimer study plan to your schedule, for example, twice a week. Then find free time and spend 8 to 10 hours a week. First, squeeze out these hours from watching TV, playing computer games or shopping, and gradually feel comfortable.
The third grade is an important period, and special periods can be stopped for special treatment. If you have your own hobbies, you must first support yourself. If you find that you can't cultivate your interest, let it go as soon as possible.
