That's a difficult one to answer 'yes or no'. It depends on so many factors. For example:
what kind of work you do and how tired you are after a shift:
how easy it will be to 'switch off' after work and get into study mode and what facilities are available for study:
your own capacity for self study and your background education:
what subject are you studying.
I guess you can give it go and see how you feel. It certainly can do no harm to try.
