I didn't study math in grade three. Can the diligent class keep up directly?
Keep up. In theory, children who can enter the diligent class have better math scores and active learning ability than those in the sensitive class. Mathematics in grade three has just begun, and there is no problem. Students who enter the diligent class can keep up with mathematics, but the admission threshold of the diligent class is also relatively high, so it is not easy to enter.
