Hello to everyone,
may you assist me with the following inquiries:
1) trying to express the situation by a verb when students in a course come and go.
May I replace it with "exchange"?
Example: I never see the same students longer time in our English course. Students just come and go.
2) the verb chisel - i always thought it might also convey the idea of making something precise or polishing skills, language, etc.
Can I use the word chisel also in a figurative way or is it uded only it the sense of manual carving?
I chisel my English speaking skills.
thanks for your time and effort
