First, study around textbooks.
Many people like to teach themselves, but this way of learning requires very high learning ability and self-willpower. These two abilities are indispensable, which wastes a good time and may not have a good result. So make full use of the advantages of the Internet!
Learning online courses should be like taking notes in class. It is suggested that you mainly underline the book, which can make the key points and non-key points clear at a glance and save energy and time when reading again.
Second, take notes and summarize the important and difficult points.
After getting the book, read it for the first time, read it carefully for the second time, summarize the key points, difficulties and doubts for the third time, and then write it in a notebook and practice it repeatedly, so as to turn all the knowledge into your own.
Third, the wrong topic reorganization, combing knowledge points
When reviewing textbooks at this stage, you only need to look at the parts you have not mastered, saving time and improving efficiency! If possible, you'd better read the test sites in the book carefully two or three times. In short, do the problem after reading the book. If you make a mistake, read the book again and do the problem again until you get it right. Although repetition is boring, you will be more confident in the exam after you are constantly familiar with every knowledge point.
Fourth, brush the questions efficiently and consolidate the test sites.
The sea tactics are the test artifacts of China candidates. Think about how you brushed the questions in the year of the college entrance examination. It is much more convenient to brush the questions now than at that time. Practice makes perfect by doing more real and simulated questions.
