Satoshi (Japanese) started from IC10 which is beginner level. She studied grammar book by herself at the beginning. She thought this was the fastest way to improve her English and it was helpful. She could understand better. However, as her English was improving, she found grammar was not very important anymore. Grammar is not the first priority but still she thinks grammar is important to improve every skill.
Maggie (Chinese) thinks grammar is most important and teacher should teach explicitly. However, it doesn’t mean the traditional grammar teaching. She found another important thing is that grammar should be how to use English not memorizing discrete elements.
Satoshi and Maggie focused on more accuracy than other students. Satoshi said “I care more (grammar) now because I have more knowledge about English.” Maggie said “I need somebody to correct me. Teacher should correct errors.”
