1. The key to English review is words, so it is necessary to take the postgraduate entrance examination for English vocabulary books. I use the English vocabulary book of New Oriental Postgraduate Entrance Examination. Personally, I think this book is not bad, and I firmly remember it through associative memory!
Grammar is also very important, but it is impossible for people who want to learn English grammar in an all-round way, so I personally suggest reviewing the grammar content of junior high school. You can read the grammar encyclopedia in junior high school and know how to analyze sentence elements to cope with the exam!
Learning English requires great perseverance, so persistence is very important. I wish the postgraduate entrance examination a success!
