What you need to do:
Finish your project.
Now that your project is generally working, implement BGI graphics for the graphical portions of your program. If your program has (or should have) graphics, it is expected that it will be working in BGI for this assignment. Simple character graphics are not acceptable.
If your program is not complete, you should also continue to work on the computational aspects of your program.
Remember that this is another three-week assignment. What you turn in should represent eight weeks worth of total work (since you are building on the previous assignments) and should include the basic program elements that you learned about from those other assignments, including classes, input/output, error checking, functions, etc., where appropriate.
