What should I know about portfolio before joining an MCA?

Portfolio is a useful area to understand in an MCA because it connects academic knowledge with practical technology work. Students should learn the concept, practise it through small exercises and then apply it in a project. If your target role involves portfolio, include at least one demonstrable project rather than mentioning the topic only as a skill. This point is specifically relevant to the portfolio aspect of MCA study. For this specific question about portfolio, the practical takeaway is to relate the concept to your own MCA learning goal.
