Personally, I think it is more convenient to update the questions in ape question bank quickly. Several teachers speak really well, so you can try a small special course.

I am a liberal arts student, so I can search the mind map app and choose my favorite style. If I type fast, I might as well use my mobile phone to do mind mapping and brainstorm.

App is generally an auxiliary role. Don't ignore the textbook and what the school teacher said.
