Difficult. Tutorial classes are generally for people with a certain foundation. I am a science major. I seem to have taken math classes for two years, such as linear algebra and calculus. After studying for two years, I am still at a loss. If you can learn well in a few months, I can only say that you are a child prodigy! It takes a lot of effort not to speak English. Don't go directly from liberal arts to science, it's too difficult!
