There are at least three ways to do this, but none of them work perfectly (depending on the number of files present and the collective lengths of their names, whether or not any of the filenames contain space or tab characters, and whether or not any of the filenames contain newline characters).

Note also that the ls utility goes to a lot of work to line up output fields while producing minimal line lengths. Converting the ls -l output to use a single tab as a field separator for all fields is likely to produce wider line lengths on display devices, and, depending on the variability of user and group name lengths, unaligned group and filename output fields.

But, before we can go into details on these possibilities, we do need clarification, as RavinderSingh13 asked, about what a "tutoring course" is.
