Four types of learning habits

Learning class Student ratio Learning characteristics
1 32.19 The class is high, the book is borrowed, the number of learning is more, the study time is longer
2 11.61 The class is not high, the book is very small, the number of studies is low, the study time is low
3 12.67 The class is higher, the book borrows more, the number of learning is more, the study time is long
4 43.53 There are fewer books, less learning and less learning time
