The reason to use c/s is because you need one central information
repository.  Unless your assignment requires multiple simultaneous users
querying and updating the database, you don't need c/s.

The reasons to go multi-tier usually involve connection speed and the
need to establish business rules (consistency or logic rules) of a type
that are inefficient to implement using SQL.

In any case since the use cost of C++ Builder 4.0 is $2,100 (upgrade),
$2,400 new I doubt that your teachers are expecting this.  Probably your
college already has a copy with the proper licensing for you to use it. 
Did you ask your teachers?
