Is there any difference in meaning between "do a course " and "take a course "?
Thanks for helping :)
There is no specific meaning of "do a course".
The verb "do" most likely means "to do the work required to study and complete a course".
For example: I did (completed) a math course last year.
"take a course" means the same thing as do a course.
For example: I took (completed) a math course last year.
The student does not have to complete the course.
Someone who did/took 75% of a course could still say that they did/took a course but then they should also mention that they did not complete the course.
