You can't really architect anything until you know what your requirements are. Continue work on your requirements homework due this week, deriving your requirements from your design, refining your design, and ultimately enumerating requirements that are precise, verifiable, conflict-free, and complete. Use this time to get feedback from the instructor and TA about these facets of your written requirements.
Before the end of class, get feedback on at least one requirement from the instructor or TA.
