keep up with the class/lecture
If am enrolled in a course, but I had some health problems and I missed classes for a month. So when I go to my first day of class, I attend the class and I am able to understand most of what the professor is explaining. At the end of the class, could I walk up to my professor and says:
"I missed one month of class, but I was able to keep up with the lecture/class today"...
Would it be wrong or odd? I mean "keep up with the lecture/class?
