How much time should I spend learning final project 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. If your target role involves final project, include at least one demonstrable project rather than mentioning the topic only as a skill. This point is specifically relevant to the final project aspect of MCA study. For this specific question about final project, the practical takeaway is to relate the concept to your own MCA learning goal.
