What projects can I build around international students during an MCA?

A strong MCA project should solve a clear problem and demonstrate real technical work. A student can strengthen it with proper documentation, testing, source control and a working demonstration. Students can judge their progress in international students by solving problems independently instead of depending entirely on guided tutorials. This point is specifically relevant to the international students aspect of MCA study. For this specific question about international students, the practical takeaway is to relate the concept to your own MCA learning goal.
