Attend remedial classes
Attending remedial classes can be said to be a shortcut. The learning style of the self-taught remedial classes for ethnic students is more flexible.
Take time to digest what you have learned.
Get used to previewing before class, and have a general understanding of the content of this class. Sometimes it is especially rewarding to go to class with questions. Take time to digest after class. Review what you have learned during the day like watching a movie when you sleep at night.
Do calendar year simulation questions and test papers.
Do some simulated test questions 15 days before the exam, and compare and analyze the test papers over the years, so that you can get a general understanding of the key points of the exam, what you passed and what you failed, and what you took this year. Some knowledge is compulsory every year.
